Near Instant Blacklists

I recently setup a 64 IP server with PMTA & Interspire. DKIM, SPF, rDNS, DMARC, IP Rotation, bounce management, return paths all setup. Before that I had setup two 16 IP servers with Postfix & Nuevomailer and ran into the same issue - I thought maybe switching to PMTA / Interspire would help.

For some reason, all 64 of my IPs ended up on Spamhaus the first blast - before I was even done sending. List is highly engaged opt ins, I got only 11 hard bounces out of my send to 35,000, sending 2 mails per minute per IP, rotating subject lines, content, IPs, domains. I'm not sure what I'm doing wrong that is getting me blacklisted so quickly?

  • So you setup a new IP/mail server then immediately blasted to 35,000 people?

    You really don't know why you are getting blacklisted?

    You have to warm up your IPs first - you can't start blasting to your full list on day one - you should divide the list into segments of about 3,000...

    Then just ramp it up daily...

    Day 1 = mail to 3,000
    Day 2 = mail to 6,000
    Day 3 - mail to 9,000

    And so on - you have to gradually warm up the IP/domain... Most suggest a 2 week warm up period...

    I only rotate 5 IPs - although I have a similar sized list - using these methods - my domain reputation has never dropped below 97. Although you will still end up on a random blacklist from time to time - just nature of the beast - however this should only be one IP and only every now and then... All 64 on the blacklist is quit the accomplishment...

    Also, if this is a "highly engaged opt-in list" why are you rotating subject lines, rotating content and rotating through 64 IPs?

    I think your deeper problem may lie within your data - are they "highly engaged opt-in" to YOUR list? Or are these cold leads to you?

    Good luck.

    • Thanks for the detailed response. I suppose maybe I don't understand the warm up process correctly. I was under the impression that most people keep it under 2K per day per IP so my thought process was to send around 500 per day per IP to warm up safe and slow then ramp up - I have much more to send than 35K. What your saying is maybe I should just send ~2K per day regardless of amount of IP's and just ramp up daily from there?

      The list is from my Rev Share partner that opts in to them - I use a service to clean the data up, and using a small package ESP I get around a 10% open rate and high click response rates.

  • I'm going to rebut what cody said.

    Those kind of mailing techniques are irrelevant really if you're using PMTA.

    with PMTA 4.5 they have their set feature in which they have auto ip warmup and they control your sending and throttle your sending when they detect a low rate on IP or on Domain.

    That's why the recommended was 150-250 per IP on warmup and if you want to be safe 50.
    Now have you checked your IP or domain if they are clean before you started sending?

    Get a Blacklist and IP monitor when you're going to send emails hetrixtools would be good since they will provide a delisting link for your IP and domain before it reaches to Spamhaus you can still recover them.

    • Thanks for the recommendation - I am going to start over with less IPs until I learn the game a little better. So with hetrixtools you can request to delist before your even listed with a provider like Spamhause?? How does that work?
  • Why if you dont know, you dont put your list to a normal autoresponder like getresponse or activecampaign or sendlane or whatsoever?

    And if u wanna pay for K emails you can go to sendinblue
