Firebase email verification goes to spam folder

Question

I made a mobile app and used Firebase for backend and authentication. When I use firebase's built in email verification, the email always goes to the junk folder / spam.

Does anyone know how to fix this?

Answer 1

That's weird. Firebase made restrictions to avoid this problem. Check here

Spam filters normally look for these things:

• Subject Line: looking for common words and phrases associated with spam.
• Content: looking for suspicious links, low text to image ratios, and other spammy hallmarks.
• Metadata: looking at the To/From/CC fields, the sender’s domain, and embedded code.
• IP address: looking for IPs that have been flagged frequently as spam by both filters and recipients in the past.

Ill suggest using your own domain to send emails. You can check this article on how to do this. You will also get the extra benefit of looking more professional.

Hope it helps :)
