How do we stop spammers from abusing our software?

Posted by David Greiner on October 28, 2005

Every now and then we'll get a question about how we ensure good delivery rates or how we make sure spammers don't abuse our software. We've just added the info to our site, but it seems to be a topic of interest so I thought I'd echo it here.

From personal experience, we know how frustrating it can be when you work hard on a campaign only to see it never get close to your recipient's inbox. We take deliverability very seriously, so here's a quick summary of some of the measures we have in place to ensure you never have to deal with this problem:

  • Our delivery servers have been whitelisted by major ISP's.
  • Our team monitors blacklists daily. If a server is ever listed (and it does happen ever so rarely), we remove it from the cluster immediately and resolve the issue on behalf of our customers.
  • Until a customer has been approved, every large campaign is reviewed by our team before it can be delivered. Any spammy campaigns are removed and the account closed immediately.
  • Our team verifies all large lists that are imported and ensures they comply with our strict permission policy.
  • Every email sent using our software contains a single click unsubscribe link.
  • Our abuse email account is monitored closely and every complaint is followed up promptly. Our software is directly integrated into abuse complaint systems for some large ISP's. If a sender receives an unacceptable number of complaints their account is terminated.

We certainly don't pretend to offer 100% deliverability, no-one can. What I can promise is that we take every step necessary to keep the bad guys from abusing our software and the good guys sticking to best practice. We apologize to any new customers who might experience a delay when their campaign is being approved, but trust me, it's definitely worth it.

I think I speak for all of our legitimate colleagues in saying great work David - keep it up. No one likes spam and knowing you guys have got our back is reassuring.

I am new to this product but find that even though you don't promise 100% deliverability, I am acheiving higher delivery rates than ever. Nice product - looks and acts great.

I would love to hear about what you to do handle ISPs that require Reverse DNS lookup.

Hey Jeremy,

As we explained in our email conversation, while we allow you to set your own from and reply-to addresses, the return-path address still points to the Campaign Monitor server so we can handle bounces for you automatically. The return-path address is the one ISP's use to perform a RDNS lookup and I can confirm these have all been set up correctly for each of our mail servers.
