Sending limits for automations

Every Sendigram account has a sending limit and a sender reputation. This article explains how the system decides how many emails to send, to which domains, and how campaigns and automations share these limits.

Campaigns and automations share one limit

Campaigns and marketing automations use the same sending limit and the same account reputation. At the same time, they are processed in separate logical queues, so one does not have to wait for the other.

  • A reserved share for automations. A minimum share of the available limit is always reserved for automations, so triggered emails are not blocked by a large campaign.
  • Unused volume is not wasted. If automations do not use their reserved share, the free volume is automatically passed to campaigns. The same works in the other direction: unused campaign volume can be used by automations.
  • The account limit is never exceeded. The total number of emails sent by campaigns and automations together never goes above the overall limit of your account.

What happens when a campaign is slowed down or paused

If a campaign is temporarily stopped or slowed down, it moves to a waiting mode and the system tries to send it again later. A campaign in this mode does not block emails from your automations: they keep going through their own queue.

Restrictions related to reputation

If a restriction is caused by the overall reputation of your account or of a sending domain, it applies to campaigns and marketing automations at the same time. For example, if a domain has a high bounce rate or many spam complaints, both its campaigns and its marketing automations will be slowed down.

How the system decides how many emails to send to each domain

Inbox providers judge senders separately. A problem with one provider should not stop your emails to all the others, so Sendigram controls the sending speed per recipient domain.

  • Major mailbox providers are controlled in their own categories, each with its own limits.
  • The Other category covers all remaining domains and has its own limit subsystem. Every recipient domain inside Other gets its own sub-limit.

In practice this means:

  • If emails to one domain go through normally, for example mail.ru, they are not affected by problems at another domain.
  • If a small domain performs badly, for example many bounces at a company domain such as auslogics.com, only sending to that domain is slowed down. Because you send only a small number of emails there, the damage to your reputation stays low.
  • Delays are expected only for domains that really produce many bounces and other problems.
