Free email health check · about 30 seconds

Find out why your emails end up in spam. Then fix it, step by step.

Before any email reaches an inbox, Gmail and Outlook check that it really came from you. If your business’s email settings are missing or wrong, your invoices, quotes and replies quietly land in spam. SenderCheck checks those settings, explains what’s wrong in plain English, and walks you through fixing it.

What SenderCheck does for you

You shouldn’t need to know how email works to make sure yours arrives. We do the technical part and tell you exactly what to do, in words you already use.

  1. Step 1

    Check

    Enter your business email or website. In about 30 seconds we look up the public settings that decide whether your emails are trusted.

  2. Step 2

    Understand

    A clear answer (healthy, or what's putting your email at risk) and what each problem means for your business, not just its technical name.

  3. Step 3

    Fix

    Step-by-step instructions for wherever your domain is managed, with the exact values to copy and paste. Then check again to confirm it worked.

  4. Step 4

    Stay protected

    These settings can break without anyone touching them. We keep checking and email you in plain English before a problem costs you customers.

Keep your email trusted, without thinking about it

Checking and fixing are always free. Pay only if you want us to keep watching and warn you the moment something changes. Cancel any time in one click.

What each tool checks

What we can’t promise: that every email reaches the inbox. That also depends on what you send and each receiver’s own filters. Correct settings are the part you control, and the part we help you get right. What we do and don’t measure
