About email spoofing issues


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 notifications@yourdomain.com, 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.


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 notifications@yourdomain.com, change the domain to notifications@yourdomainblogs.com. 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.


Other solutions

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 asking LexBlog to confirm the records in MailChimp:

    Type: CNAME
    Name: k1._domainkey.yourdomain.com
    Value/data: dkim.mcsv.net
    : Default

    Type: TXT
    Name: yourdomain.com
    Value/data: v=spf1 include:servers.mcsv.net ?all
    TTL: Default
