Your customers say they never got your email

You sent it. It's in your sent folder. But the customer swears it never came. How many more went missing that nobody told you about?

Updated · senderframework.com

Signs this is happening to you

  • A customer asks why you never replied, but you did.
  • People say "check your email" and find nothing from you.
  • Quotes and follow-ups get no answer, more than they used to.
  • Someone finds your email weeks later, in their junk folder.

Why are my emails not being received?

Every email you send is judged before it reaches anyone. The big email companies ask one question: is this really from you? If they can't tell, they put your email in spam or junk, or drop it and tell no one.

Nothing looks wrong on your side. There is no error. Your email just doesn't arrive, and you find out weeks later, from an upset customer.

Why doesn't anyone warn me?

Because no one is looking. Your email company sees the email leave. The other side sees it arrive, or not. Nobody sits in the middle and tells you what went wrong.

That is why so many businesses lose email for months before they notice. The problem is real the whole time. It is just silent.

Why is it so hard to find the cause?

The cause is almost never one big mistake. It is a small detail in the settings behind your email, set up years ago, or changed by someone who has since left. Some of these details are so small that even a skilled IT person can look right at them and say all is well.

And they change. A tool you added, a service you closed, a date that came and went. What worked last year can stop working this week.

What is it costing me?

A missed email is a missed reply, a missed sale, a missed payment. Worse, the customer doesn't know it was missed. They think you didn't bother.

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.
