The send rate limiter allows you to slow down the delivery of a communication when you want to control the volume of traffic generated by your email. This is especially useful when your message contains links to websites, landing pages, or restricted areas that could be affected by too many simultaneous visits.
Why limit the sending speed?
By default, magnews sends communications at the maximum speed available, which can exceed hundreds of thousands of messages per hour.
In some situations, however, delivering messages more gradually can be beneficial.
For example, you may want to:
- avoid overloading a website linked from the communication;
- distribute traffic over a longer period;
- reduce the risk of too many simultaneous requests reaching your systems.
How the send rate limiter works
When you enable the send rate limiter, you can specify the maximum number of messages that magnews should send per hour.
Once the limit is set, magnews distributes message delivery according to the value you defined.
Minimum sending speed
The lowest value that can be configured directly is:
- 60,000 messages per hour
- 1,000 messages per minute
If you need a slower delivery rate, you can contact the Help Desk and request a lower limit.
The sending speed can be reduced to as little as:
- 600 messages per hour
- 10 messages per minute
How values are managed
Sending speed values are processed in multiples of 60.
If you enter a value that is not a multiple of 60, magnews automatically rounds it down to the nearest valid value. For example, if you enter 60,128, the value is automatically converted to 60,120.
When should you use a send rate limit?
A send rate limit is useful whenever the success of a campaign depends not only on email delivery, but also on the capacity of the destination systems receiving the resulting traffic.
Typical examples include:
- communications linking to a landing page;
- campaigns driving traffic to a website;
- messages directing recipients to restricted-access areas;
- initiatives where traffic spikes should be avoided.
