I was recently testing the responsiveness of my mailing lists. And I came to the conclusion that leads from my double opt-in list are more responsive than the ones in my single opt-in list. So I decided to write this short post to explain the difference between those two kinds of opt-in mailing lists and why you should prefer double opt-in for your email marketing campaign.
We have to kinds of mailings lists:
– Single opt-in where emails are not confirmed before being added to a mailing list. That means that your visitor can subscribe to your list quickly but also anybody can submit a misleading email address or one which is not their own and be automatcally added to that list.
– Double opt-in on the other hand requires that email addresses are confirmed before being added to a mailing list. An autoresponder service will send a request for confirmation to the email address that was submitted and the owner of that email account must click on the activation link to confirm their request for being added to that mailing list.
Double opt-in contributes to keep your email list clean and responsive. That because people who subscribed to your list had to confirm their interest in being added to your list twice and they confirmed that they are the real owners of the email address which was submitted.
That will prevent you from malicious subscriptions and false spam complaints. When using double opt-in you are acting accordingly to the CAN-SPAM act.
