1. User sentiment
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Average Rating | 4.5/5 (2,000+ reviews) | 4.0/5 (350+ reviews) | 4.2/5 (2,000+ reviews) |
| Setup Experience | A few minutes - 48 hrs for validating domain authentication | Quick setup — a few minutes to a couple of hours for domain authentication. | 5-30 mins setup with short video series. |
| Learning Curve | Easy multichannel setup with intuitive interface | Developer focused, Getting Started guide for new users | Intuitive interface, video modules available for new users |
| Best for → | SMBs needing affordable multichannel marketing | Technical teams needing scalable, API-first email delivery. | Brands that value ease of use, strong design flexibility, and guided support for quick adoption |
Brevo works well for SMBs that want multichannel marketing with an intuitive interface. The tradeoff is setup variability—domain authentication can take up to 48 hours, which may delay time-to-launch for teams moving fast.
SendGrid is optimized for technical teams that value API-first email delivery and quick authentication. Its developer-focused experience and learning curve make it less ideal for marketers who want plug-and-play campaign execution.
Campaign Monitor stands out for brands that prioritize ease of use, design flexibility, and guided onboarding. With a 30-minute average setup and built-in video modules, it’s the most accessible option for teams that want to get productive quickly without technical friction.
"Campaign Monitor’s user interface is very good. It is one of the most simple email marketing tools I have personally used, with clear areas for one-off campaigns, automation and report viewing. Setting up automated email campaigns is very simple and painless, again, something that is a very strong selling point for the platform.”
2. Design & user experience
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Email Editor | Drag-and-drop editor with responsive templates; Developer Mode for advanced customization | Flexible, hybrid editor; no-code drag-and-drop interface with a powerful HTML code editor | Intuitive drag-and-drop email builder with HTML customization, auto-branding |
| Template Library | 40+ free responsive templates for newsletters, promos, and welcomes | 300 templates or versions per user, with responsive import and reuse. | 150+ mobile-optimized templates with auto-branded options |
| Design Flexibility | Brand Library auto-applies logo, colors, and fonts | Switch between visual editor and code for custom control | Auto-branded templates from website URL, dynamic content and custom fields |
| Branding Consistency | Brand assets sync automatically across templates | Customizable HTML and modules for brand-aligned emails | Auto-branded custom templates |
| Best for → | Businesses needing simple, responsive design with built-in brand control | Developers needing flexible, code-friendly email design | Marketers who value high-quality, professional design without complexity |
Brevo works best for teams that want simple, responsive designs with built-in brand control. Its smaller 40+ template library keeps things manageable, but limits flexibility for brands that need high-volume or highly polished creative.
SendGrid deprioritizes design in favor of delivery, offering little in terms of templates or visual tooling. This makes sense for API-driven teams, but it’s a poor fit for marketers who need fast, on-brand campaign creation.
Campaign Monitor stands out with 300+ mobile-optimized templates, auto-branding from website URLs, and flexible customization via HTML and dynamic content. For marketers who care about professional design without hands-on effort, it offers the cleanest, most scalable experience.
"Campaign Monitor's drag-and-drop editor feature helps to save time to build templates… Easy to track & mobile friendly templates are more powerful than its competitors."
3. Automation & journeys
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Trigger Options | Time, date, behavior, and custom events | Time-based, behavior-based, and event-based triggers (sign-ups, purchases, inactivity) set in advance | Time-based, behavior-based, and event-based triggers (opens, clicks) |
| Conditional Logic | If/then branching with multiple conditions | Exit criteria supported; no full visual if/then builder | Advanced if/then branching |
| Prebuilt Journeys | Welcome, abandoned cart, birthdays, re-engagement | Prebuilt Welcome Series; others built manually | Prebuilt automated journeys, such as welcome series, abandoned cart, anniversaries, and events |
| Journey Complexity | Cross-channel: email, SMS, WhatsApp + send-time optimization | Customizable drip flows with timing and exit rules | Focused on email-centric journeys, but offers SMS as well |
Brevo fits teams that want easy automation across email, SMS, and WhatsApp without heavy setup. Its if/then branching covers common lifecycle needs, though journeys stay relatively straightforward rather than deeply layered.
SendGrid handles event-based triggers and custom drip flows, but the absence of a full visual if/then builder limits flexibility for marketers. It’s best for technical teams comfortable assembling journeys manually.
Campaign Monitor stands out with advanced if/then branching and a strong set of prebuilt journeys for onboarding, recovery, and milestones. For teams wanting clear logic and reliable automation without engineering work, it’s the most complete option.
"Wonderful Union saved 40 hours weekly using Campaign Monitor's automated email marketing campaigns and saw a 13% increase in CTR on automated sequences, generating a 700% ROI from email marketing campaigns."
4. AI Features
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| AI Content Creation | AI Writing Assistant creates or improves subject lines, emails, and campaigns | No AI writer; AI supports personalization, real-time content, and automation. | AI Writer for brainstorming, refining copy, adapting content for new audiences, generating captions, and optimizing CTAs |
| Design Intelligence | AI Assistant adapts tone and refines draft content | Dynamic and interactive emails that adapt to recipient behavior. | Personalized copy suggestions and auto-branding |
| Optimization Tools | Send-time optimization and subject line testing | AI-powered email validation, neural protection, and deliverability insights. | A/B testing with insights & goals (opens, clicks, site visits). |
| Predictive Features | Real-time engagement insights with recommendations | Churn prediction, anomaly detection, and send-time optimization (via API integration with AI tools). | Send-time recommendations & time-zone sending. |
| Best for → | Marketers wanting practical AI tools for faster campaign creation | Technical teams prioritizing deliverability over AI content. | Marketers needing AI-driven content inspiration and audience-optimized messaging |
Brevo’s AI is built for practical efficiency. It helps marketers write faster, adjust tone, and optimize send times, making it useful for teams that want noticeable gains without changing how they already work.
SendGrid’s AI focus is infrastructure-first. There’s no AI writer, but predictive tools support validation, anomaly detection, and deliverability, which matters most for technical teams running high-volume or API-driven email systems.
Campaign Monitor puts AI where it directly affects results: copy quality, timing, and optimization. With built-in A/B insights and send-time recommendations, it’s the strongest option for teams prioritizing polished messaging and audience alignment over raw technical control.
5. Deliverability & performance
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Delivery Rate | High delivery rates (No stated overall percentage specified) | 99.5% delivery rate | 99% average delivery rate* (among the best in the industry) |
| Inbox Placement | High inbox placement supported | Dedicated IPs, ISP feedback loops, and automated warm-up | Strong sender reputation with mailbox providers; dedicated team optimizing for consistent inbox placement |
| Deliverability Tools | Domain authentication (SPF, DKIM, DMARC), shared/dedicated IPs with warm-up, list hygiene best practices | Deliverability Insights dashboard, bounce/spam diagnostics, domain authentication (SPF, DKIM, DMARC), suppression management | Inbox previews, spam testing, deliverability experts, in-app authentication guidance (SPF, DKIM, DMARC), dynamic list hygiene tools |
| Sending Reliability | Real-time performance dashboards; delivery rate monitoring by IP or campaign and set alerts for drops. | Real-time performance metrics, adaptive delivery with ISP-specific pacing, and engagement tracking | Real-time performance dashboards with bot-click filtering; trend monitoring to support sender reputation |
| Best for → | Businesses needing consistently high inbox placement with dedicated support | High-volume senders needing advanced deliverability monitoring and technical control | Businesses that want expert deliverability guidance and proactive support to maximize inbox placement |
Brevo is built for teams that want reliable inbox placement without deep technical overhead. Its authentication tools, warm-up support, and hygiene practices make it a safe choice for businesses that need consistency more than fine-grained control.
SendGrid is clearly optimized for scale and technical precision. Dedicated IPs, ISP feedback loops, and adaptive pacing matter most for high-volume or API-driven senders that actively manage deliverability as an engineering concern.
Campaign Monitor stands out for expert-led deliverability, not just tooling. Inbox previews, spam testing, real-time reputation monitoring, and a dedicated optimization team make it the strongest option for brands that want proactive guidance to maximize inbox placement, not just metrics.
"Campaign Monitor has very good deliverability, which was an issue with other newsletter management systems. Campaign Monitor sends a large volume of emails (both with frequency and large numbers of subscribers) without deliverability issues, which drives significant traffic to our website, and provides revenue via sponsorships and advertisements."
6. Segmentation & personalization
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Segmentation Capabilities | Real-time auto-updating segments based on custom fields | Create dynamic segments using custom fields, reserved fields, and engagement data (opens, clicks), updated hourly via Marketing Campaigns UI or API | Rule-based segmentation using subscriber data (custom fields, activity, location, demographics) with AND/OR logic; unlimited segments per list |
| Dynamic Content | Dynamic blocks with if/else and data feeds | Handlebars templates for conditional copy, images, and formatting | Dynamic content blocks using if/else logic and custom fields |
| Personalization Tags | Attributes like name, email, birthday for subject/body personalization | Per-recipient substitutions using dynamic_template_data via API | Supports default tags (name, email) and up to 50 custom fields (birthday, country) |
| Subscriber Preferences | Profile update forms + multi-list subscription options | Preference and unsubscribe links managed on SendGrid-hosted pages | Fully customizable preference center (fields, frequency, topics) |
| Best for → | SMBs needing simple personalization and dynamic targeting | Teams needing dynamic, condition-based personalization via API and granular segmentation | Marketers seeking comprehensive preference management |
Brevo is best for teams that want hands-off personalization that updates in real time. Auto-updating segments and basic dynamic blocks work well for SMBs running straightforward campaigns without needing technical setup or API work.
SendGrid leans heavily toward developer-controlled personalization. Dynamic segments, per-recipient substitutions, and API-based logic suit teams that want precision and scale, but it places more responsibility on engineering to manage complexity.
Campaign Monitor delivers the most complete marketer-led segmentation experience. Unlimited rule-based segments, flexible custom fields, and a fully customizable preference center make it the strongest choice for brands that need control, compliance, and personalization at scale—without relying on developers.
The Australian Red Cross used Campaign Monitor's preference center and smart segmentation to achieve a 68% increase in open rates, a 201% increase in click-through rates, and a 75% increase in conversions from a single personalized email campaign.
7. Integration ecosystem
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Number of Integrations | 150+ native integrations across CRM, ecommerce, and productivity apps | Pre-built and custom via partners (AWS, Google Cloud, Heroku) | 250+ integrations with focus on quality |
| CRM Integrations | Salesforce, HubSpot, Microsoft Dynamics, Pipedrive | Salesforce and others through partners like MassMailer, Zapier | Shopify, WooCommerce, MailSync |
| E-commerce Integrations | Shopify, WooCommerce, BigCommerce, PrestaShop | Integrates with Shopify, Magento, WooCommerce | Integrations with various CRM platforms (Salesforce, Zoho, Zapier) |
| API Flexibility | Open API with full documentation, webhooks, SDKs for custom use | Robust Email API with dynamic templates and personalization | Robust API for custom integrations |
| Best for → | Teams needing reliable access to key ecommerce and CRM tools | Developers needing API-first, customizable integrations | Marketers working with major platforms seeking quality |
Brevo is strongest for teams that want plug-and-play access to core CRM and ecommerce tools. Its large set of native integrations reduces setup friction, which matters when speed and operational simplicity outweigh deep customization.
SendGrid is built for developers who want control, not convenience. Partner-based integrations and a powerful email API work well for custom stacks, but marketing teams may rely more on engineering to connect and maintain systems.
Campaign Monitor focuses on quality over volume. Its integrations target major platforms marketers actually use, paired with a robust API for edge cases. The result is cleaner data flow, fewer workarounds, and easier long-term management for non-technical teams.
Girls Who Code leveraged Campaign Monitor's Salesforce integration with custom fields for deeper list precision, helping them achieve a 40% email open rate, 22% click-to-open rate, and a 150% increase in student applications.
8. Pricing & scalability
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Starter Offer | Free plan (300 emails/day, custom email templates, drag-and-drop editor, SMS & WhatsApp campaigns) | Free trial (100 emails/day for 60 days, no credit card) | 30-day free trial (500 contacts, 500 email sends, 3 users, drag-and-drop builder, templates, basic reporting) |
| Most Popular | Business: $18/mo (5,000 emails, automation, AI, A/B testing, phone support) | Essentials $19.95/mo for 50K–100K emails/month; includes analytics, deliverability optimization, 1 teammate, 2 event webhooks, no email validations, and dynamic templates editor | Essentials: $29/mo ($2.90 first month) — unlimited contacts & email sends, inbox preview, automations, AI Writer, transactional emails, priority support |
| Pricing Model | Tiered plans: Free → Starter ($9/mo) → Business ($18/mo) → Enterprise (custom); pricing based on email volume, with annual plans offering ~10% discount | Tiered plans: (Free Trial → Essentials $19.95/mo → Pro $89.95/mo → Premier custom pricing | Tiered plans: (Free → Lite $12/mo → Essentials $29/mo → Premier $159/mo) with unlimited emails from Essentials upward |
| Best for → | SMBs seeking affordable entry and unlimited contact storage | Developers and teams needing scalable, pay-as-you-go email sending | Best for brands wanting predictable, lower-cost entry plans with strong email features and optional SMS add-ons. |
Brevo is best for SMBs that want to start free and scale gradually. The free plan and low-cost Business tier make experimentation cheap, which matters when budgets are tight and contact growth is unpredictable.
SendGrid suits developers and high-volume senders who care about cost control at scale. Pricing is tied closely to send volume and technical usage, which works well for transactional or API-driven email, but less so for marketing teams needing bundled features.
Campaign Monitor is built for brands that want clean, predictable pricing as they scale. Unlimited sends from the Essentials plan remove volume anxiety, making budgeting easier once email becomes a core, recurring channel rather than an experiment.
"We use Campaign Monitor because it is quite easy to use… It is also very reasonably priced. We haven't had any problems with deliverability or in creating the emails."
9. Support & resources
| Feature | Brevo | SendGrid | Campaign Monitor |
|---|---|---|---|
| Support Availability | Email support on Free & Starter; Business adds chat; Premium includes phone support. | 24/7 ticket and chat support for paid plans; phone support and Technical Account Manager (TAM) access via Personalized Support add-on (starts ~$5,000/mo) reaching highest-priority assistance |
|
| Support Response Time | Well-regarded; Priority response for Business & Premium tiers. | Paid plans get standard help, while Personalized Support offers SLAs: 1 hr for P1, 2 hr for P2, 3 hr for P3 issues | Fast response times praised |
| Knowledge Resources | Help center, courses, and community | Knowledge Center with extensive docs, guides, and Support FAQ | Extensive help center, Knowledge Base, training videos, and email academy (even on free plan) |
| Onboarding Assistance | Tailored onboarding on Enterprise plan | Optional Professional Services available Optional Professional Services for onboarding and deliverability help. | Professional services team available |
| Best for → | Businesses needing email support and rich self-help resources | Technical teams needing self-service with optional expert support. | Brands seeking fast, expert-led support with global availability. |
Brevo works well for SMBs that prefer self-serve help with backup human support. Email support on lower tiers and priority response on paid plans are enough for routine needs, but hands-on help is limited unless you move up.
SendGrid is built for technical teams that value structured, SLA-backed support. Tickets, chat, and optional paid services matter when uptime and deliverability incidents need formal escalation, though premium help comes at a clear extra cost.
Campaign Monitor stands out for brands that want fast, expert-led support without add-ons. Phone access, deliverability specialists, and strong global coverage reduce friction when email is business-critical, not experimental.
"Been working with Campaign Monitor for 10+ years… Not only does the platform make sending highly-customized emails easy and fun, their support team is phenomenal… Highly recommend."
