Rather than sending your email to its intended recipients in a single blast, it is possible to send in timed batches to slow down a send. This is often a good idea to help manage resources in your organisation, from staff dealing with enquiries, to websites being able to handle traffic, or orders being picked and packed efficiently.
Checking the box on the Send screen labelled Batched Sending will allow you to specify two parameters:
|Batch Size||The number of contacts to send in each batch.|
|Delay||How long Sentori should wait before picking up the next batch of contacts to send to.|
An organisation with a small sales team wish to email their list of 5,000 contacts. In order to manage their daily workloads they decide to send their email over the course of a week. To achieve this, they set the Batch Size to 1,000 contacts, the Delay to 24 hours, and schedule their email to send at 8am.
The result is a batch of 1,000 emails being sent every day for five days at 8am.
In planning a batch send, it is useful to understand the speed at which your batches can be sent. Whilst there is no set speed, the following variables will affect your send rate:
As a very rough rule of thumb, users of our shared service with a clean list could consider an approximate maximum send speed of ~60,000/hour. In reality, we have senders who achieve much more than that and some that achieve a lot less.
Once an email has started batch sending, it is possible (via the Cancel/Reschedule option on the email's cog menu) to cancel the remaining batches and have the remainder of the emails (excluding the current batch) send in a single group.
