Check your approved senders list (SPF checker)

Your approved senders list names every service allowed to send email as you, like your email host and your newsletter tool. Type your website's name and we'll check it in seconds. Free, no sign-up.

We read settings anyone on the internet can see. We change nothing. The check covers all your email settings, not just this one.

What it is

Approved senders list (SPF). Names the services allowed to send email as you. Email from anywhere else looks fake.

Why it matters

If a service you use is missing from the list, its email can land in spam. If the list is broken or too long, it may not work at all, and fakes in your name get through.
