Hi, I'll be interested in hearing/seeing how it goes. I implemented Sendgrid for the Braillists when I was volunteering with them for a bunch of automated email reminder systems I'd built: we were seeing a 5 to 7% block rate on our messages (look at blocks under the statistics section of the dashboard) with Microsoft-owned addresses being the main offenders. We had a feeling that the real number was actually higher based on feedback we received, but ultimately weren't really able to pin down the issue - E.G. was it a non-technical person not knowing they had received the message etc. We had a bit of a back and fourth with support over this because as you know one of the big selling points of the service is its delivery rate, but ultimately the answer we got was to purchase a dedicated IP from them (by default your messages are sent using a pool of shared IPs) but we couldn't really justify the cost. Maybe you'll have better luck though; we were using their Transactional Email product and I'm guessing you're using something different? Cheers, Ben.

Hi.
For me what has killed it is lack of email sending or sporadic sending. When I ran the lists for BCAB I sent out nearly 5000 emails a day and had very good response rates for removing Ips from blocklists etc. These days I am lucky if I get a response and its most often a no. Having my own email rejected by Office365 this morning was the last straw.
Andrew.

Honestly its really hard work running a mail server these days that isn’t one of the big companies.
I've noticed the same, although I have succeeded so far in not ending up on a block list with any of the large providers. I suspect intermittent delivery issues from this address, but I don't have any clear evidence that it's a result of being hosted on my own server.
My other e-mail address is with Microsoft 365, which gives better fault tolerance and spam filtering than I can implement myself. On the other hand, Microsoft 365's spam filter generates false positives as well, sometimes for legitimate mailing list traffic from a large provider - resolved for now by placing the affected addresses on an allow list.
