How to send a campaign in batches

As an alternative to sending a campaign to all recipients at the same time, you can use Batch Settings to set the campaign to send in batches over a number of hours or days. This enables you to review times and days which see a better response level as well as helping you to keep enquiry and responses manageable when sending to very large audiences.

Advanced Options

Batch Settings can be found in the Detail tab of Campaign Setup screen. They are hidden by default in the Advanced Options section. So select "Show Advanced Options" to display the settings.

Batch Settings Fields

Once you can see the Advanced Details section, the Batch Settings options are in the middle of the left column

Batch Volume

Batch Volume

The first field allows you to set a batch volume from a predefined list. The minimum batch size is 5 emails. The maximum is 500,000.

Batch Frequency

Batch Frequency

The second field allows you to set the batch frequency to either "Per day" or "Per hour"

Initiating your campaign with Batch Settings

Initiating your campaign with Batch Settings

Once you have set these two variables, you can initiate your campaign as you would normally. CommuniGator will then automatically batch contacts from your total audience and send the campaign in batches either hourly or daily after the campaign is initiated. The last batch may be smaller than the others where the audience is divisible by the Batch Volume. E.g 102,000 contacts in batches of 10,000 will send ten batches of 10,000 and one batch of 2,000

NOTE - Continuous Sending

Please note that CommuniGator will continue to send in batches based on your settings on a continuous basis. This means that campaigns will continue sending through the night if set to Per hour or through the weekend if set to Per day. To avoid sending emails at unwanted times, ensure that your Batch Volume is set so that the entire audience is sent the campaign in the desired timeframe. E.g: Sending 500,000 emails Monday to Friday only - You would need to initiate your campaign on Monday and set the Batch Settings to 100,000 per day



Very useful I will be trying this out.


We send large numbers to single organisations and fear that this spamming will result in an org blocking our emails. Is batch sending known to improve deliverability?

Kia Irving

Hi Ellen, generally, yes it can help as it slows down the rate of which emails are being sent out. But there's more to deliverability than that. Have you tried our Inbox checker and SendForensics plugins in the campaign test tab? I'd recommend having a chat with your account manager if you're concerned about your campaigns impacting on your deliverability score.
