DKIM trouble with infusionsoft

How I fixed my problem

Why use DKIM: It helps your email to be tagged as legitimate communication versus being seen as another piece of junk in the flood of spam across the WWW.

DKIM won't verify?

The problem: You've set up DKIM using the infusionsoft tool (under settings in your infusionsoft dashboard) but after hitting the "verify" tool, it says "not verified."


  1. Have you copied over the DKIM key information correctly?
  2. Did you copy it perfectly but put it into the configuration wrong?
  3. Everything is correct but it still won't verify!

If you haven't already reviewed the Infusion Soft official help page here it is.

The "Dangling Dot" problem

You enter the DKIM key into the appropriate place for your website setup, but when you go to check on it, there is an extension made to your entry, such as:


But it should look like this:




in fact the resolving domain doesn't look right either, it looks like this:


But it should look like this:




Solving this "Dangling Dot" problem

When you enter the DKIM key be sure to leave at the end of the entry a DOT:

Example: dkim.infusionmail.com.

Absense of that DOT can cause the server to (incorrectly) add in additional identifying information.

The Blocked Verify Issue

All the settings are correct and you still can't get the Infusion Soft verify tool to acknowledge it. Possibly the Infusion Soft tool cannot SEE your settings.

What happened: It is possible that during the verify query, your server (where your web site is) reacted to the Infusionsoft tool as if it were an attack, and blocked the Infusion Soft tool.

How to solve this: Either you (or your hosting provider) will need to access the list of blocked IP addresses on your server, find the Infusionsoft IP, and delete it from the prohibited connection list. It may be under "Firewall Deny IPs" - - the IP range will probably look like this: (you can call on Infusion Soft support to provide the IP range).

After deleting the IP from the blocked list: Go to the verify tool in your Infusion Soft dashboard (under settings) and use the tool again. It is possible you will need to wait up to 24 hours for the verify to then work if you have recently used the tool and got a 'not verified" result.
