Previously, we added real-time notifications to our growing family of integration features. Since then, we’ve sent over 100,000 email addresses via the new platform to Campaign Monitor and MailChimp. To keep up the momentum and help make using those services even easier, we are excited to announce the ability to create Single Opt-In and Double Opt-In mailing list sign-up forms in Wufoo for those two integrations.
First, let’s do a terminology overview. Because you want to avoid setting up a situation where users feel like they were duped into joining your mailing list, Opt-In features allow you to avoid accumulating bad karma by giving your users the chance to choose whether or not to be added to a list.
- Single Opt-In allows your user to choose on your form whether or not he/she wishes to join your mailing list.
- Double Opt-In will also send your user an email reminding him/her of his/her decision to join your list. The user will not be added to the list until h/she clicks on a link sent in that email. This is to prevent a nemesis from signing up users for lists without their permission and to make sure that the email addresses you’re going to send out to are verified.
If you’d like to do some more reading about the value of Opt-In options and the pros and cons of each, the guys at MailChimp have provided a great write-up describing them in detail.
Single Opt-In for both MailChimp and Campaign Monitor can be set up directly in the Wufoo interface in the Notification Settings. All you have to do is create a form with a checkbox field and then select that field for basing whether the user accepts being added to the mailing list under Only Send If Choice Is Ticked.
To set up a Double Opt-In form for MailChimp, it’s very easy. Just tick the Send Opt-In Email setting in the integration settings and it will send a verification email to the user with a link to verify that they really want it. For Campaign Monitor, because Double Opt-In is set up at the list level, you’ll have to log in to their service and set it up via their interface to make it work. You can learn about how to do that in our Campaign Monitor Integration Docs.
