MessageFlow Booster is a campaign booster feature designed to increase message reach by automatically triggering follow-up sends or an alternative channel when a predefined condition is met. It operates across SMS, email, and push and is managed directly in the MessageFlow panel without turning your campaign into a complex workflow.

What is Message Booster?
MessageFlow Booster is a simple, condition-based mechanism that helps recover campaign reach and revenue when the first touchpoint doesn’t land. Instead of re-sending to your entire audience, you define a rule such as “not opened” or “not clicked,” and MessageFlow automatically targets only the recipients who didn’t engage.
This means that if the primary campaign is ignored or missed and doesn’t generate the intended interaction, a second attempt can be sent either in the same or via another channel, depending on your MessageFlow plan.
How Message Booster works
Campaign Booster operates through four clearly defined stages:
When creating your campaign, you activate the Booster feature directly in the user panel. You define the triggering condition (e.g., “if the recipient does not open the message within 24 hours”) and prepare the follow-up message in the selected channel.
The main campaign launches as planned and is delivered to the entire selected target group.
The system automatically monitors user activity within the defined time window (e.g., no open, no click) and identifies recipients who meet the specified condition.
After the selected time period expires, the platform automatically sends the prepared follow-up message (email or SMS) exclusively to recipients who did not engage with the original communication.
Selectivity is key here. The booster targets only the audience segment that didn’t engage, helping you extend reach while avoiding unnecessary duplicates for recipients who already interacted.
Supported channels and Booster logic scenarios
MessageFlow Booster can operate within the same channel or across channels, depending on your selected plan and campaign configuration.
Second attempt in the same channel
This scenario involves sending a second message within the same channel, targeting only recipients who did not engage with the original communication.
- Email → Email (resend with adjusted subject line or timing)
- SMS → SMS (second message if no interaction occurred)
This approach works well when you want to increase message visibility without switching the communication channel.
Intelligent channel switch
In this scenario, the second message is delivered through a different channel, typically one with higher visibility or urgency, if the initial communication did not produce engagement.
- Email → SMS (channel change if the email was not opened)
- Push → SMS (escalation to a more direct channel)
In cross-channel scenarios, Booster helps balance cost, reach, and urgency by reserving the more direct channel for recipients who did not respond to the first contact.
When should you use Message Booster?
Message Booster is designed for marketing teams that want to maximize the performance of their campaigns without manual list work or building complex automation workflows.
Your newsletter contains a strong offer but it gets lost in a crowded inbox. Booster allows you to automatically re-engage recipients who didn’t open the first email, for example, by adjusting the subject line or sending at a different, specified time.
A limited-time promotion is about to end, and part of your audience hasn’t checked their inbox. An automated SMS follow-up to non-openers increases visibility instantly and helps recover potential sales before the opportunity closes.
Push notifications capture attention, but they’re often dismissed without interaction. If a user doesn’t engage, Booster can trigger an SMS message that remains visible on the device, giving recipients another opportunity to return to your offer.
Operational benefits
In other words, you keep the campaign simple, while the platform handles the “what if they didn’t see it?” layer.
No need to manually build additional segments
How to activate Message Booster
Message Booster is available with all paid plans and can be utilized directly in the MessageFlow panel as part of the campaign flow.
Transparent pricing model
MessageFlow Booster is not a paid add-on or separate module. The mechanism is included in all paid plans, with no activation fee and no requirement to upgrade to a dedicated automation subscription.
The billing logic is simple:
- No activation fee: Booster is built directly into the campaign creator. You don’t pay for enabling the automation mechanism itself.
- Messages deducted from your package pool: Follow-up messages are counted against your available message volume. Once the package limit is exceeded, messages are billed according to your standard CPM rate.
- Channel scalability based on plan: The Starter plan supports Email → Email follow-ups. The Grow plan enables cross-channel scenarios (e.g., Email → SMS). The Advanced plan extends capabilities to include mobilepPush based scenarios.
Don’t let unengaged recipients limit your results.
