Customers can set a custom email send rate for campaigns to control how quickly messages are delivered.
Lowering your send rate can help protect your systems and teams by spreading activity over time and reducing the risk of traffic spikes to your website or support channels. It can also strengthen deliverability by creating a more consistent sending pattern that builds trust with receiving servers, which is especially valuable for re-engagement campaigns.
When scheduling your marketing email campaigns:
Our system will send your email campaign no faster than the specified rate. If throttling is not enabled, our system will send as fast as possible.
