Double opt-in for email

See also: Double opt-in for SMS

Double opt-in allows your recipients to confirm their subscription status.

This is especially important if you're sending to countries where marketers are required to demonstrate explicit marketing consent. 

As well as double opt-in for any of your Ometria-based subscription forms, Ometria supports double opt-in links which you can use in any email from Ometria.

You can also define which URL the contact should be taken to after clicking the double opt-in link, and have the option to add those contacts to a segment.

While double opt-in is not mandatory under GDPR, it is considered a best practice in several European countries - particularly Germany.

In Europe, you can't send unsolicited marketing communications without the recipient's consent.

Link format

The format for double opt-in links is:

https://api.ometria.com/forms/confirm?profile={{profile.hash}}&account={{email.account_hash}}&next_url={{url}}

Add this link behind the subscription CTA in your email templates.

This link will automatically sign up every contact that clicks on it and redirect them to your homepage.

Redirecting the double opt-in link to a web page

Your double opt-in link will direct recipients to your homepage by default.

To redirect your recipients to a different page on your website, add &next_url= to the end of the link, followed by the URL of your preferred page.

Example:

To take the recipient to https://www.yourbrand.com/blog/ add &next_url=https://www.yourbrand.com/blog/ to your double opt-in link:

https://api.ometria.com/forms/confirm?profile={{profile.hash}}&account={{email.account_hash}}&next_url=https://www.yourbrand.com/blog/

Redirecting the double opt-in link to your preferences centre

To redirect the email recipient to your preferences centre, you can use the shortcode string preferences after &next_url=

Example:

https://api.ometria.com/forms/confirm?profile={{profile.hash}}&account={{email.account_hash}}&next_url={{prefs}}

Adding contacts to a segment

To add recipients of your double opt-in link to a segment, first find the segment ID in Saved segments, then add &add_confirmed_to_lists=[segment ID] to the end of your link.

Example:

To add the recipient to a segment with the ID 383, append &add_confirmed_to_lists=383 to your link: https://api.ometria.com/forms/confirm?profile={{profile.hash}}&account={{email.account_hash}}&next_url=preferences&add_confirmed_to_lists=383
