Also using PurelyMail, tt's the cheapest non-free email service I can find.
It passes email delivery tests, setup SPF, DKIM and DMARC easily without issue.
The downside is that it's basically one man handling whole this service, but I assume this service has been fully automated because the margin of profit is so low.
Yep I signed up this year and been using it with no issues. Such a good service for the low price. If it was not automated then I don't think it could be that low priced.
