| I used Hetzner. At the time I allocate an IP address, it's was listed on DNSBL.
I tried like 30times to get a good IP and gave up. I instead just allocate a new IP, wait a week. Started to send email to myself every 15minutes to a gmail address. Anytime it isn't showed up in Important, I go in to move it to important. If it showed up as spam, I marked it as not spam. After 2-3 weeks doing that, The IP is no longer listed on any blacklist and I started to roll them out. Don't worry too much about IP blacklist. They aren't super important to gmail. If an IP stopped sending spam, they will be removed from IP blacklist eventually. Give it a week. > "a sizable daily volume of email traffic (up to the order of hundreds)". I send about 8,000 emails per day and somehow that Postmaster Tools not reports anything at all. I would say If you send me an email vinh@hanami.run I can tell you what you can do to avoid being flagged at spam. Happy to jump in a 1-1 chat https://calendly.com/vinh-hanami/15min to help you on that. |
