It’s new, it’s improved, it’s faster than ever…The new Email Marketing sending engine is now available for beta testing in version 4.54.6. Details to turn on the beta engine are below.
With the new sending engine you will see faster sending speeds. Below you will see a comparison for sending speed:

To use the beta sending engine:

  1. Open your /12all/admin/ file
  2. Put the following code in a new line right above the line that has “?>”
  3. Your 1-2-All installation is now using the beta sending engine.

Remember, there are also other factors that go into email deliverability. The email sending speed only relates to what is happening on your own server, not the recipient server.
