I promise, this takes only seconds.
For non-Gmail users:
If you’re using any email client other than Gmail, visit whitelist.guide and choose your email provider.
For Gmail users:
If you are using Gmail, the only foolproof way to whitelist a sender is to create a filter that categorizes the sender’s emails as belonging in the Primary inbox. This is not complicated at all, and takes less than 20 seconds. (It can only be done in a browser, though, not in a smartphone app.)
First, click the three dots in the right-hand corner of the email and choose “Filter messages like these.”
Then, make sure the “From” line says “firstname.lastname@example.org” and click “Create filter.”
Finally, check “Never send to Spam,” Categorize the email as “Primary,” check “Also apply filters to matching conversation(s),” and click “Create filter” again.
🎉 That’s it! Now you can enjoy receiving the emails you signed up for.
