It's been two months since I am running a mail server. I worked on a beautiful UI like SendGrid and MailGun for more than six months. I plan to start a transactional email service.
I bought a range and rented another /24 range because I didn't want to have a bad neighbour on the subnet. I even got my own ASN because jerks like UCEProtect often put big ISPs on a blacklist at the ASN level.
Of course, I have got a decent experience with this. I wrote my own SMTP server, email routing, and other things such as bounce and suppression handling. In a sense, everything is fine. RDNS, DKIM, DMARC, and SPF.
I know that IP needs to warm up, so that's where I started. I paid for a few services to help me warm up, and it took me about two months to do so. Okay so far. The email was delivered 100% of the time to Gmail, but not at all to Yahoo and Outlook. The delivery rate to these two companies started to get better around last week, though. Some IP addresses started getting a 100% delivery rate.
Then, I started testing my service on one of my websites. Of course, 100% transactional emails with account confirmation links ONLY. It was working great. Nearly 2,000 emails, 3,000+ opens and about 2,500 clicks daily on an average.
I've also subscribed to Glock Apps and MXToolbox to measure my email deliverability and monitor IPs.
Just today, I received an email with all half of my active IP addresses and sending/tracking domain blacklisted by Spamhaus. They categorize it under "spam domain", but I looked through my server logs (yes, everything is logged) and found no evidence of spam. Only transactional and warmup emails sent. I opened a ticket with Spamhaus and refuse to unblock my IP addresses and domains.
I spent 6 months and $20,000+ working on this, only to be butchered by Spamhaus. I want to kill myself. How can Spamhaus be the police, judge and the executioner?
Haha. UCEProtect are biggest cunts who ask for money for whitelisting. We tend to ignore them.
Did you ask spamhaus for headers of email IDs they marked as spam? Or did they give any reason?
Also, who is using your service?
They did not provide any reason and just mentioned that they are unable to remove the block at the moment. Now, my replies are being ignored.
Only I am using the service (warmup + transactional emails sent through my other site) right now. I haven't started selling the service to others yet.
What are the warmup emails exactly?
Basically, services like Folderly run their own private network of email addresses (on G Suite). Their service opens and interacts with emails, simulating real user behavior, to test and improve email deliverability and sender reputation.
snake oil, basically. you're hoping very hard Google doesn't detect their service and just ignore it or worse.
Yeah, it's a bit hard to say whether they work or not. This is why I added my own website with real users interacting with confirmation emails
Some warmup services are better then others due to pool size and esp distro. I really good one that has worked for me for long is smartlead a popular cold email tool with a big pool and unlimited warming in its small cheap plan. Some Tools like folderly are smaller and newer and don’t work as well. Smartlead also has a much more stealth warmer nails that isn’t obvious with stupid big footprints like code ls in the subject line that are easy to detect (for use with rules and moving those emails to other folders). Make sure to set a good reply rate percentage, replies are critical to email rep
Please stop shilling your product
Does my history make it look like im shrilling products on here. Try to help with advice and you get this shit. If I owned fukin smartlead with that many clients I’d be rich as fuk and certainly not be here wasting time shilling anything to a few random people
