How fast does ActiveCampaign send email?

We have a high-end mail delivery infrastructure allowing us to quickly deliver your emails.

Many people ask us how long it takes to send X emails per min/hour/etc.. There is no way to give a definitive answer to this.

In theory we can send to a single list of a million subscribers in under an hour.

There are however some factors that can affect delivery times:

  • Your list quality
    Lists that have lower quality (low interactions, high bounces, high abuse, etc..) will often be delayed/slower.
  • Your subscriber's domain
    Some ISPs may delay or require that we slow down and throttle when sending to your list. So if the majority of your subscribers are with such an ISP, it could bring down the speed.
