I’ve been using phpList for about a decade on a shared server using localhost. The software is great - thanks. From time to time, though, someone else spamming on the server means everyone gets blacklisted. I just have about 5,000 subscribers and send 20,000 or so emails a month.
I see you now use Discourse for the forum, which recommends Mailgun, SendGrid, Mailjet and Elastic Email.
Are these, or others, recommended for phpList?
I will also look into phpList.com - but I will need the email server also for other things too (like Mailman) so am not sure it would be suitable.
I note that in signing up to the phpList forum, both the Wordpress confirmation email and the Discourse confirmation email went to my Gmail junk folder, which I suppose demonstrates how hard it is to get right.
