A really handy way of ensuring as many people as possible see your emails is to set up a re-send to everyone that didn’t open the campaign when it was first sent.
When you’re scheduling your campaign, as usual, go to campaigns and then select schedule campaign.
First you need to select your list, then the message you’re going to send to. Then on the final page, you’ll see a section called resend to non-opens.

Here, enable the re-send, and then you’ll get the option to select how long you want to wait until the re-send starts. It’ll be worth leaving it at least a few days before the re-send starts, as you’ll want to give people the chance to see it before sending them another one.
You can also select the subject line you want to send it with- we’d recommend using a different one to the one on the first send, as there was probably something about it that didn’t engage with people that made them not want to open it.
Once its all set up, schedule your campaign as normal, and then later, your Pure360 account will look to see who’s not opened it yet, and they’ll get sent a follow up email.
