LeadServe for Campaign Monitor allows you to display your list opt-in invitation to targeted consumers on hundreds of websites and mobile apps.

LeadServe gives people the ability to subscribe to your list without making those people come to your website or your store first. Signup forms on your own website are an important list growth tactic, but LeadServe is very different. LeadServe uses patented technology to display your signup invitation on hundreds of participating third-party websites and mobile apps. Try it now and get the first $25 worth of new subscribers absolutely free.

How It Works

With LeadServe for Campaign Monitor, you select your desired geographic and demographic targeting, and LeadServe displays your opt-in invitation to targeted consumers visiting hundreds of premium websites and mobile apps, from publishers like Time Inc. and Hearst. New subscribers are immediately loaded directly into your Campaign Monitor list. And you only pay for new subscribers. It’s that simple. Really.

Frequently Asked Questions

Q: How much does LeadServe cost? A: You will pay a small fee for each new opt-in subscriber. That’s it. There’s no set-up fee or monthly fee. If you try LeadServe and no one signs up for your list, you will never pay a cent. In fact, you’ll even get the first $25 worth of subscribers for free if you sign up today.

Q: How can I redeem the $25 credit? A: Your account will automatically be credited with $25 when you create your first signup campaign in LeadServe. LeadServe will generate new subscribers until the $25 credit is fully spent. After that, you’ll be prompted to enter your payment details if you’d like to continue building your list with LeadServe.

Q: Great, but why would a website want to display my signup form? A: Because the website earns part of the fee you pay when someone subscribes to your list on their site.

Q: That makes sense, but I don’t have much time on my hands. What does it take to get started? A: LeadServe was designed for simplicity. Getting started usually takes about five minutes. Just follow the prompts in the LeadServe set-up wizard.

Q: What if my audience is just the people in my town? Can I still use LeadServe? A: Of course you can – we LOVE local businesses! If your business is local, simply tell LeadServe to target only potential subscribers in the relevant ZIP codes.

Q: How about if I’m only interested in women between the ages of 35 and 45? Can I target my audience in LeadServe? A: Yes you can. Just tell LeadServe the demographic profile of the subscribers you’re looking for and it will find them for you. One of the best things about opt-in advertising is that you only pay for a subscriber who wants to be on your list. However, targeting can help you maximize opt-ins from your best customer segments.

Q: But do subscribers actually sign up for my specific list? A: Absolutely. With LeadServe, you can rest assured that your new subscribers have explicitly signed up for your list. If a website or app visitor wants to join more than one list, she must make a unique selection for each desired list. LeadServe is powered by Opt-Intelligence, the leader in opt-in advertising for more than a decade.

To get started with LeadServe, all you need is a Campaign Monitor account, your API key and the List ID for the list that you’d like to add your opt-ins to! LeadServe will take care of the rest. To get started or for more information, check out the LeadServe site!
