Email confirmation from sign-up goes to spambox

[LucasWalters]

Describe the bug
This will not be the case for everyone but on my gmail account, the email asking for confirmation after sign-up on Playabl went to my spam box. Likely because it is very bare. Email effectiveness of bypassing the spam filter can be tested through services like these: https://www.mail-tester.com/

To Reproduce
Steps to reproduce the behavior, cannot be reproduced for everyone:

1. Sign up for playabl using your email
2. Wait for email confirmation
3. Find email in spambox

Expected behavior
For the email to pass the spamfilter as it is not spam.
