Published specifications, published prices, and no tier that hides either
Written by the people who run the platform rather than by a content team, which is why some of it is blunt about what does not work.
Stop your mail going to spam
Three DNS records decide whether your mail is trusted. All three are set for you when mail is hosted here.
## SPF
Lists the servers allowed to send for your domain. One SPF record per domain, no more.
## DKIM
Signs each message so the receiver can tell it was not altered. The key is published as a TXT record.
## DMARC
Tells receivers what to do when SPF and DKIM do not line up. Start at `p=none`, read the reports for a fortnight, then tighten it.
## If you send through something else
A newsletter tool or a shop sending on your behalf has to be added to SPF and given its own DKIM key, or its mail will be treated as a forgery.
