How to improve email deliverability


Onyx from PowerMTA Ninja talk about How to improve email deliverability and I find it useful. 

He said a popular question and I really look forward to days that I don’t have to answer how to improve your deliverability so let me try to answer this so I can later just point everyone to it.


improve email deliverability

First, let’s make one thing clear. This isn’t your average guide on how to improve email deliverability that will tell you always use double opt-in blah blah blah.

Since my customers usually don’t have double opt-in lists we’ll focus on other ways to improve email deliverability. But of course, we must touch some the well-known ones as well.

The boring

This are all the ones you should already know that includes but are not limited to:

  • Subject lines should be related but catch readers attention
  • Use a subdomain for all sending activities
  • Don’t send to hard bounced contacts twice
  • Remove soft bounces after 3 – 4 bounces
  • Make sure you use SPF and DKIM
  • Avoid spam traps
  • Use feedback loops (FBL)
  • Don’t over mail
  • Don’t add attachments
  • Keep your email size small
  • Use spam checker before you send
  • Make unsubscribing easy and instant

The part they don’t tell you

Ok, this is where things get interesting and a lot more technical. Please for the love of email god don’t try to do this on your own if you don’t have enough knowledge. You will make everything even worse and in the end, you will blame me. I am telling you now. This is hard as I simply can not write a guide you can just copy/paste. Every system is different so there are a lot of adjustments and thinking on your end. Maybe it would be better if you check my services.

No? Ok, but don’t blame me if you screw everything up.

So what do you need to improve email deliverability?

First, you need a software to make your SMTPs smarter so they will be able to:

  • IP rotation
  • Domain masking
  • Ability to spin content to avoid getting spammed
  • DKIM signing
  • SMTP based limits
  • Domain specific limits
  • Automatic bounce processing
  • Automatic feedback loops processing
  • And so on

Next, you need a better email marketing software. I’d say you are stuck with Interspire or similar like Mailwizz or ARP Reach. Maybe it’s time to forget about those and move on with time and use something modern but still familiar enough so you will not spend 2 weeks learning the basics.

Well, aren’t you in the right place? I have a step by step guide to set up the server yourself with Mumara. It is like Interspire Installation of Maborak Addons. You can use 1 main server and control the rest of the Power MTA.
