How do I integrate my site with MailChimp?

For basic integration, all you need to provide is your MailChimp API Key and List ID. We take care of the rest.

To get those two, follow these steps:

  • Login to MailChimp
  • Navigate to Account > Extras > API Keys
  • Copy the API Key which looks like 12ab34cd567890-us2
  • Navigate to Lists > (Name of List To Add To) > Settings > List Names and Defaults
  • Copy the List ID, which looks like 1ab3c34567
  • If used by FWD:labs on your behalf, we will encrypt these credentials so they are extra secure

To add the API Key and List ID to FWD:labs, see Account > Integrations when logged in.

For deeper authentication, validate / authenticate the domain with DKIM and SPF records.

  • Login to MailChimp
  • Navigate to Account > Settings > Verified domains
  • Enter the "from" e-mail address you have with the domain

As of 2017, MailChimp asks for the following:

  • Login to your DNS
  • Connect to MailChimp with DKIM
    • Add a CNAME record
    • Key: k1._domainkey.[domain name goes here]
    • Value:
  • Connect to MailChimp with SPF
    • Add a TXT record or edit if you already have one
    • v=spf1 ~all
