Campaign Booster is a feature that gives you a second chance to approach your customers and grab their attention if they skipped the Campaign for the first time.

To ensure that your subscribers are not getting too many emails from you, Campaign Booster can only be sent to those who didn't open or click the initial campaign.

According to our estimates, it may bring up to 30% in the open rates compared to the initial sent.

Before You Begin

  • If you already sent the campaign, a booster won't be available for the campaigns sent to less than 100 recipients. On the other hand, if you add the booster before sending the campaign (when setting it up), it'll be sent even if there are fewer than 100 contacts.

  • Campaign booster may get canceled if you don't have enough email or SMS credits or if it exceeds your daily limit.

  • Campaign Booster is available on all the Omnisend plans.

  • Campaign Booster is scheduled and sent automatically.

  • The iOS 15 update impacted this feature. More info here.

Enabling Campaign Booster

To turn on the booster, proceed to the Review step of your campaign creation and move the toggle under the Campaign booster feature.

Here, you can select booster channels: you can pick either an Email or SMS channel.

For the email channel, you can edit the Campaign booster’s subject line, content, and sending rules. You can send a booster message to those who have not opened the initial email or have not clicked the initial email.

We suggest using a completely different subject line for the boosted version. This way, you will get a perfect chance to send a reminder for your promotion and not be too annoying to the customer.

You can also choose when to send a booster message. The default timeframe is set to 48 hours.

Please note you will see an option "send together with email," which should be applied to the SMS channel (not email) and only if you want to send the SMS at the same time the email is sent.

The content of the booster email will be automatically copied from your original email. You can preview the content of the email by clicking Preview. If you want to make changes, click on "Edit Content". Once done editing, click Save & Close.

If you decide to boost your campaign with SMS, you must create SMS content from scratch. You can do so by clicking the Create SMS button. The process is the same as creating an SMS campaign. Once ready and you have reviewed the price, click Save & close.

Please note that your recipients should be subscribed to the SMS channel to receive booster SMS; you will see an error text if none of them are subscribed.

Once you have created the SMS, you will see the SMS credits needed for this campaign and your current SMS credit balance. You will also be able to edit the SMS.

Tip💡 If you choose to send SMS (booster) only when the subscribers don’t open or click your email instead of regular SMS campaigns, you’re likely to spend fewer SMS credits.

We have set the 48-hour gap as a default for the Booster because of good practice. Within this time gap, it becomes clear who has noticed your email and opened it and who of the subscribers have missed it forever.

Note you can click on the Boost campaign button that will be available for the next 46 hours after the initial Campaign is sent if you forgot to set the booster during the Review step.

After enabling a Campaign Booster for your initial Campaign, another campaign will be scheduled (with different subject lines) in the Scheduled Emails tab. This campaign name will start with "Booster of:"

If you decide that the boosted version should not be sent, you can always cancel it by clicking on the Restore to Drafts button.

Editing Boosted Campaign

A Booster campaign cannot be edited once scheduled. If you restore it to Drafts, it will lose the Booster status, and it will be sent to ALL your subscribers instead of just the non-openers. Be careful!

The only way around this is to create a Segment of the customers that didn't open your initial Campaign and schedule a Boosted Campaign for them.

Step 1: Create a Segment based on the not opened message filter and specify the title.

Make sure to use Message sent filter to ensure that your message is received by the intended audience.

Step 2: Select the recipients' list in Campaign settings.

Campaign Booster Reports

Campaign Booster reports can be found on the Reports tab, next to the rest of the campaigns. To separate from regular Campaigns, we add Booster of: at the beginning of the campaign name, which is only seen to you and not your subscribers.

Once sent, all of the stats for the Boosted Campaign are separated from the original one. If you need to Segment your customers based on the sending data, you may also refer to them as two different Campaigns.


What could cause the erroneous status for the Boosted Campaign?

We recommend checking all of the requirements, but according to our experience, it could happen if you run out of email or SMS credits.

Is it possible to Boost the A/B test Campaign?

No, it is not possible. Nevertheless, you may use our segmentation to see that newsletter non-openers.

My booster campaign was sent out earlier; why did it happen?

The only reason why a booster campaign can be sent out earlier is if you use the Timezone optimization feature. If this feature is used, the booster campaign is sent precisely 48 hours later than the initial email (depending on the time you set) for each client. Still, if you compare the time when the first booster email is sent to the scheduled time, it might seem that the Booster has gone out earlier. Don't worry; it just means that some customers in your audience have a different timezone than the one set in your Omnisend account.

Suppose I'm sending a campaign with an 'excluded' segment selected. If a contact who received the original campaign is added to that segment, will they be excluded from the booster?

Adding contacts to excluded segments for the original campaign will not exclude them from the booster campaign.
