Some firms may not receive their own email campaigns if the send from domain is identical to the firm email domain. If your email system receives an email from firstname.lastname@example.org, but has no record of sending a message out from that address, the system may block the message. This security measure is used to prevent spoofing attacks.
Changing the send from domain
If spoofing causes your campaigns to be blocked, the most effective solution is to change the email campaign send from address to another domain your firm manages.
For example, rather than sending MailChimp campaigns from email@example.com, change the domain to firstname.lastname@example.org. This address must have a working inbox, as MailChimp will send a confirmation code to verify the domain.
Note: Campaigns cannot be sent from a Gmail account, and MailChimp discourages sending from another free email service.
If your firm cannot change the send from domain, your IT team may try some of the following steps:
- Whitelist to accept all incoming emails from the send from address.
- Whitelist MailChimp's IP addresses.
- Whitelist the campaign's subject line.
- Set up custom DKIM and SPF authentication by adding the records below to your domain's DNS records. Then ask LexBlog to confirm the records in MailChimp:
