Emails from MailChimp still continue to land in SPAM?

October 2, 2022  |  2 min read

There have been complaints about issues while utilizing MailChimp and SPF. Because MailChimp employs a shared IP address for all of its users, any number of domains’ SPF lists may contain the IP address resulting in email deliverability issues.

It’s possible that MailChimp’s use of a shared IP address is to blame if you’re utilizing it and experiencing issues with email delivery. The IP address could be included on the SPF list for any number of domains as a result of this, which then results in problems with email delivery. In this article, we will be looking at some of the Mailchimp integration problems.

MailChimp Integration Problems

A common problem Mailchimp users face is being unable to send bulk emails from Mailchimp’s domain because the SPF record hasn’t been added,

In the “MAIL FROM” field, where the domain is extracted for SPF verification, Email Service Providers (ESPs) like Mailchimp frequently employ their own addresses to handle returned-mail scenarios for your campaign. For the most part, you want them to do this.

Because the domain being used for SPF authentication is not yours, this strategy ensures that your raw SPF cannot fail. However, SPF relative to DMARC will fail misalignment because the SPF policy domain does not match the “From:” header domain.

The raw SPF result will be a “pass” against servers defined by the SPF record at the servers.mcsv.net address. However, traffic will continue to flow as long as you put up DKIM because DMARC requires either SPF, DKIM, or both for authentication. Make sure your DMARC reports indicate that all MailChimp traffic is successfully passing DMARC on the basis of DKIM by checking your DMARC account.

How to Set up SPF for Mailchimp

We will be looking at setting up SPF for Mailchimp in this section to avoid this problem.

Add a second TXT record, this time for the bare domain you added as your transmitting domain, to enable SPF. The modal will once more ask you to create a new TXT record with a domain name and value when you click View SPF settings.

The value should be, at the very least: If you solely use Mailchimp Transactional to deliver mail for that domain.

include:spf.mandrillapp.com?all v=spf1

If you already have a TXT record with SPF information, you must include include:spf.mandrillapp.com in the record in order to include Mailchimp Transactional’s servers.
