Double Opt-in
Using single opt-in allows people to subscribe directly to Lists without first verifying their email address. The risk with this approach is that the quality of data captured can be lower because of spelling mistakes, typos and spambot activity.
Double opt-in is a much better approach and operates using a two step email addresses confirmation process. The first step is to capture a persons details (Forms, API etc.) and the second step is to automatically email a confirmation link for them to click.
It is not until the confirmation link is clicked that their opt-in status is confirmed and some of the benefits of this approach are:
- Assurance of valid email addresses
- Confirmation of consent to receive emails
- Protection against spambots, email scams and fake subscribers
- Reduced complaint rates
- Higher open and click rates
