Hi Akabueze!

Have you checked the spam folder?
If the mail is there then consider this:

1. You’re setting the from email to a none existent email.
2. You’re setting the from email to an email that the target never received an email from.
3. You’re setting the from email to an email of a domain that correctly implements DKIM, DMARC and SPF, currently only %4 of domains implement them properly.

So please try again keeping the above notes in mind and you should be able to get your email to land in the inbox.

Hope it helps!
Diego
