Emails not going to Hotmail/Gmail/Yahoo/Aol/Outlook/Comcast? Blocked

Many People ask questions my emails blocked by Hotmail or yahoo or gmail or aol means my ips become blacklisted so I want to change my service provider what you suggest I always say bad idea!


Its normal issue when you send emails to unconfirmed or non optin lists or from any new server, ips or domain to even your existing subscribers they can be blocked. Reason could be any of the followings

  1. Because of spammy content / subject line / links.
  2. Too many emails from cold ip and domain.
  3. Due to high bounce rate.
  4. Domain is already used before and had bad reputation
  5. Etc…

To fight with this issue you need to check your email logs and contact your email service provider they can be helpful not all but some knows the game and they can fix it for you.

Some people think that because there emails not going to gmail or Hotmail or yahoo or aol so its mean their ESP is bad and they should change the service provider. Which is a wrong approach if your emails going fine to Yahoo or Gmail or Aol or Hotmail any of the big ISP then I will suggest you to not change the ESP or ips or server.


It’s true your emails not going to Hotmail but changing of ESP or IP will take you to same point from where you started. If luckily your ips and domain got warmed up with gmail or yahoo or aol and emails going fine and you getting opens.

Then you don’t need to change ESP or IPs all you need is get more ips and domains for the blocked ISP and send all future emails of blocked ISP from new domain and IPs and try to warmed up. And keep sending emails from old IPs and domain to the ISP which were accepting your emails.
