Domains & DNS
Newsletters or website emails landing in junk
If emails sent on your behalf by another service land in people's junk folders (or don't arrive at all), the usual cause is missing sender authentication. Examples are newsletters from Mailchimp or ActiveCampaign, website contact forms, booking systems, and invoices from accounting software.
Why it happens
Mail systems check your domain's SPF, DKIM and DMARC records to see whether a service is allowed to send email as you. If the service isn't listed, the email looks like a fake and gets filtered.
How to fix it
- In the sending service, look for a setting called domain authentication, sender authentication or verify your domain. It'll give you some DNS records to add.
- Raise a ticket and paste in those records (or a screenshot), along with the service's name. A technician will add them. See DNS explained.
- Once they're added, go back to the service and select Verify (or Authenticate).
Other tips
- Send from an address on your own domain (for example a news@ address), not a free email address.
- Avoid link shorteners and lots of images with little text. These trigger spam filters.
- If only your own staff aren't getting the emails, it may be your Microsoft 365 filtering. See An email you're expecting went to Junk or quarantine.
