I followed step by step all the tutorial and followed all the instructions of this video.
It works, only for 1 day... I repeated the steps, procedure and it worked... for 1 more day...
The issue is that I'm using a GMAIL account, and SendGrid blocked 2 times my both gmails.
Then I tryed, for a 3 time with Yahoo Mail but it didn't works ever.
I'm wondering if there's any solution with GMAIL that be permanent. Can you please share the Code I need to use for GMAIL, please?
