I would be more interested in having RSS/Atom feeds than emails since I already follow some forums like that, but I have no qualms with emails existing on here.
My company has used Brevo when it was still called Sendinblue for manual mass mailing, and they're considering replacing the email setup on our apps with Brevo. Certainly better than the current random OVH mail account that occasionally hits rate limits… I haven't been involved in that either but I didn't hear of any major issues.
