There are constant issues of password resets not working, emails to certain accounts like yahoo or msn accounts because Bubble uses SendGrid.
I switched out to Postmark and haven’t looked back since.
They have an offer of $75 free for bootstrapped startups, which is most of us on Bubble.
I just wanted to share this link with you all because this is a constant issue. Hope that helps!
You can also use this link to give us both a free month of paid service: Friends & Family Program
