We had been sending out around 1000 e-mails per day using G-Suite (via SMTP), and with new features being released we projected that we would exceed G-Suite daily 2000 message limit. So we moved over to SendGrid with the expectation of no more than 100K message per month, and chose the 20.00 plan that was in line with our volume requirements. Within 4 days Yahoo/AOL mail became deferred because Shared IP's were being blacklisted based on other users mail practices. So we were stuck, the only way to address the issue was to upgrade to a PRO plan at 4 times the price, so that we would be sending mail over a dedicated IP address. I never got the feeling that support was trying to resolve the issue, but instead were explaining the problem, and offering the upgrade path as the only solution. It was as if their pool of shared IP addresses was one deep, and if it became blacklisted that was it. I got the feeling that this was an up-sale approach, rather than an issue I just happened to run into after 4 days as a new customer. Not sure what we will do, but I upgraded today just to get our mail moving again. After 72 hours of sitting in the outbound queue, the mail will simply be discarded as undeliverable. Do not use this service unless you start out on a dedicated IP plan. Otherwise it's completely undependable.
