Didn't get the activation email? Here is why

An activation (or verification) email contains a link or code that proves the address is yours. When it does not arrive, the cause is almost always one of five things, and most take a minute to fix.

Quick answer

Check Spam or Junk (and Gmail's Promotions tab), search your mail for the company's name, then check you typed the address correctly. Wait a few minutes, then use the site's Resend button once. Clicking resend over and over can lock you out for a while.

Free tool: check an address or a list right now with the EmailNa email checker. It catches typos, throwaway domains and domains with no mail server.

The five usual causes

  1. Spam or Junk folder. Automated emails often land there. Also check Gmail's Promotions and Updates tabs.
  2. A typo in the address. gmial.com, hotmial.com and .con instead of .com are common. Run the address through the email checker.
  3. Delay. Busy services can take several minutes, and codes are occasionally delayed longer.
  4. Too many resends. Each new email can cancel the last one, and repeated requests can trigger a temporary lock.
  5. Your mailbox is full, or a filter you set up moves or deletes the email.

What to do, in order

  1. Search all your mail, including Spam, for the company name or "verify".
  2. Check the address shown on the site's screen.
  3. Add the sender to your contacts (for Google, [email protected]; for Microsoft, codes come from @accountprotection.microsoft.com).
  4. Wait 5 to 10 minutes, then request one new email.
  5. Use the newest link or code only. Older ones usually stop working.
  6. Still nothing? Contact the site's support and ask them to confirm the address on file.

Activation links are deliberately short-lived. Go back to the site, sign in or start again, and request a fresh link. Then open it soon after it arrives.

How to spot a fake activation email

Running a website? Fewer missing activation emails

Check addresses at sign-up for typos and throwaway domains, publish SPF, DKIM and DMARC for your sending domain, and send activation emails from a recognizable address. Test your setup with the DMARC and SPF checker.

Questions people ask

How long does an activation email take?
Usually seconds to a few minutes. If nothing arrives after 10 minutes, check Spam and the address you entered before you ask for another.
Why do I get a new code every time I click resend?
Each request creates a new code and cancels the old one. Use only the most recent email.
What does activating my email mean?
It means clicking the link or entering the code the site sent, which proves you own the address so the account can be used.
