Campaign Booster

Not everyone opens an email the first time. Campaign Booster sends your campaign again, with a new subject line, only to the customers who missed it. People who already engaged never get it twice.

Boost a campaign

1. Open a campaign that finished sending in the last 48 hours.
2. Press Boost this campaign.
3. Choose who gets it: people who have not opened the email, or people who have not clicked it. Gro shows how many people each option reaches.
4. Write a new subject line, and a preheader if you like. A fresh angle works best, for example “In case you missed it” or a different reason to open.
5. Choose how long after the original finished sending it goes out, in hours or days. The longest is 3 days.
6. Press Schedule booster.

The booster is its own campaign, so you can see its opens, clicks and sales separately, and it shows in your campaigns list and calendar like any other. It has a Booster label that links back to the original, and the original has a View booster button.

Set it up before you send

On the Review step of a new email campaign, turn on Campaign Booster and fill in the same choices: who gets it, a new subject line and how long after sending. When the campaign finishes sending, Gro schedules the booster for you. If nobody is left to boost by then, it’s skipped.

Who gets it

• Have not opened: everyone who received it but didn’t open or click it.
• Have not clicked: everyone who received it but didn’t click it, including people who opened it.
• Worked out when the booster sends. If someone opens or clicks the original before the booster goes out, they’re left out too.
• Only people you can still email. Anyone who has unsubscribed since is never included.
• Apple Mail opens. Apple Mail can mark an email as opened without the person reading it. Gro doesn’t count those as opens by default, so those people get the booster. If you’ve turned off Exclude Apple Mail Privacy Protection opens, they count as opened and are left out.

Good to know

• 48 hours to set it up. You can boost a campaign for 48 hours after it finishes sending, while it’s still fresh. After that, the button tells you the window has closed.
• Ask Gro Agent. Say “resend the summer sale to people who didn’t open it”. Gro Agent tells you how many people missed it, suggests fresh subject lines and sets the booster up. When you send or schedule a campaign without a booster, Gro Agent offers one in that campaign’s chat. Nothing is set up until you press confirm.
• One booster per campaign. You can’t boost a booster.
• Email campaigns only. Text message campaigns can’t be boosted yet.
• Same email, new subject. The booster uses the original’s email template. If you’ve edited that template since, the booster sends the edited version. To send something different, create a new campaign instead.
