Today we are going to explain what a double opt-in subscription means, although we believe that most users already know what this concept means, it is a critical point to creating successful email campaigns and maximize the delivery rate of your newsletters.
A double opt-in subscription is basically a subscription with confirmation by email. That is, the system will send an email with a link for the user to confirm that he wants to receive your newsletters.
Benefits
1- It is possible to ensure that no one is registered on your mailing list by third parties without the user’s consent, which prevents spam complaints.
2 -You will be able to confirm that the email address is real, is active and correct, thus avoiding a new bounce and consume unnecessary credits.
3- It prevents malicious competitors from adding spamtraps or problematic emails in your databases to ruin your sender score reputation.
4-It offers the opportunity to take advantage of the confirmation e-mail to send additional information or a presentation.
Compliance with local laws
In addition to all these advantages, the double opt-in process is required by many countries. For each country the law may vary, regarding electronic communication, but it is better to be safe. It is also important to remember that many ISPs are from other countries, and will follow different laws.
It is also important to remember a fundamental point, that many users forget. You need to keep a record of all IP logs, subscription date, to prove the user has registered on your mailing list.
This is critical to be able to prove that the user signed up voluntarily, for a certification audit, for instance by ReturnPath.
If you use the Mailrelay subscription form and the confirmation email is sent with an account with statistics, log signature, you can access your dashboard whenever you need this information, (clicking on subscribers for example).
