Your email went wrong after a change

You moved to a new email company. Or built a new website. Or started sending from a new tool. Soon after, people stopped getting your emails.

Signs this is happening to you

  • Trouble started after a move to Microsoft 365 or Google.
  • A new website went live, then form emails or receipts went missing.
  • You added a new tool for newsletters, bookings or invoices.
  • Someone "tidied up" your settings, and now things are worse.

Why would a change break my email?

The settings behind your email are shared by everything that sends in your name. Change one part and another part can break, with no warning.

A new website builder may quietly replace a setting. A new email company may need a line your old one did not. A tool you stopped paying for may still be named, and now counts against you.

Why didn't the person who made the change see it?

They tested what they changed, and it works. The part that broke is somewhere else. It only shows up when the wrong email goes to spam, and by then no one links it back to the change.

How long has it been broken?

Often since the day of the change. Without someone watching, the first sign is a customer who asks why you never wrote back.

What we find that others miss

These are small things. Each one is enough to send your email to spam, or let a fake through.
