The best practice in email marketing is to use a double opt-in subscription method (also called "Confirmed Opt-in" or COI). There are many reasons:
Sometimes, however, recipients that wanted to subscriber forget to confirm their subscription (or don't see the subscription confirmation request).
In the scenario described above (someone wants to subscribe, but doesn't confirm his/her intent, for whatever reason), triggered messages can come to the rescue!
An automated follow-up message can be the perfect solution, reminding the subscriber-to-be to confirm their subscription. In fact, a couple of follow-up messages could be sent at different intervals.
Let's see how this is done.
First, create a new message in MailUp to ask the pending recipient to confirm their request.
Make sure that the message is short and to the point, and test it to ensure that it does not trigger a spam filter because of its content.
The subject of the message should also be clear about what the recipient needs to do. For example: "Your Company Name - You forgot to confirm your email address" or alike.
Now that the message is ready, you can easily configure your MailUp account so that it sends it automatically a day after the recipient has become Pending.
To add a new Triggered Message, click on Marketing+ > Automation > Tasks.
Set it up as follows:
Use the simulation feature to simulate what would happen if the task were run at that moment: it should give you a number of recipients that equals those that signed up a day before, without confirming their subscription.
Here is a visual example of how the Event trigger section would look.
We recommend that you follow these guidelines when implementing automated, follow-up messages to pending subscribers:
Test this with your own "seed list" (a number of different email addresses at different ISPs) or work with our Deliverability Team, if you subscribed to the Delivery+ service.
