How do I setup DKIM records to improve email deliverability?

This article applies to you only if you are a paid plan subscriber (Silver, Gold, or Agency) and are using MailMunch's autoresponder feature.

Why do I need DKIM Setup?

Let's say you own a company My Pancakes with domain mypancakes.com. You setup an autoresponder that goes out from jessica@pancakes.com. Since you haven't setup DKIM keys, your emails will be signed by MailMunch's domain and your subscribers will see the following headers in the email:

Some Email Service Providers (ESPs) mark emails as spam if the signing domain is not the same as the sending domain. In this case:

Signing Domain: mail2.mailmunch.io
Sending Domain: mypancakes.com

Unmatched domains raise a red flag and can result in your emails going into spam or not being accepted at all in the first place.

 

How do I setup DKIM on MailMunch?

MailMunch lets you setup DKIM signing keys for your domain (mypancakes.com) so that any outgoing emails that we send on your behalf are also signed by your own domain. To do that, follow these instructions:

1. Click "Manage Site" on the top navigation bar.

2. Click on "Domain & Emails" tab.

3. On the following page, you'll see your domain name added under the "Domains" section. If you don't see it, simply add it by entering it in the text box that says "Enter Domain" and hit the "Add Domain" button.

Click on the "Fix It" button against your domain name.

 

4. You'll see a modal similar to following. Note down the key and value for your DKIM record.

Note that the Key is the bold part and not the full domain. In the above screenshot, the key is: scph0517._domainkey

 

5. Once you've copied these values, you need to create a TXT Record for your domain with your domain registrar who's hosting your domain name servers. Here's a list of the most common ones:

 

6. Once you've created the TXT record for your domain, you need to tell MailMunch to verify it.

Click on the "Verify Records" button and we'll perform verifications for your domain.

 

7. Once the verifications are complete, you'll see the following notice:

How do I verify that my DKIM records are actually working?

All emails with proper DKIM setup will look like this:

Note that the "signed-by" domain and the sending domain are same and therefore, ESPs will not mark this email as spam for signing mismatch reasons.
