Pre-Flight Checks

Am I ready to click that send button?

  • Am I on a blacklist?
  • What are my spam scores?
  • Are my authentication policies like SPF and DKIM right?
  • Has our technical infrastructure changed?
  • Are my links valid?

We know the answers, and we’ll tell you in real-time if there are problems so they can be fixed before it’s too late.


Even our best senders have problems that crop up nearly every month

In-Flight Monitoring

I’ve clicked that send button.  How’s it going?

  • Are we blocked by Gmail, Yahoo!, or other ISPs?
  • What do I do with these bounce messages?
  • Is my engagement where it should be?
  • Did we end up on a blacklist?
  • How do I fix these problems?

Normally, it might take you hours or days to identify a problem, let alone fix it.  Email Copilot handles all of this in real time.

The faster you fix problems, the faster your email program can generate its full revenue potential
