A: Hi,

It's Alex, the founder of ProxiedMail.
Thank you for reaching out.

I would recommend just to test with more realistic emails.
Also, never send from the same email as your real email - it wouldn't work.

Additionally, marking as not spam would help in a future cases.
Over all sometimes it might end up in spam as all real emails if you never received it before.

But if you're constantly using it - no.
