Is an unsubscribe link required?

If you have marked an Engage email as transactional in the advanced settings, eg. for an order receipt or subscription renewal email, then an unsubscribe link won't be added. Abusing this feature and marking emails as transactional when they aren't will result in your Engage account being suspended.

Whenever sending a non-transactional email from Metorik, a clearly-visible and functional unsubscribe link is required.

You can only use Metorik Engage to send emails to customers that consented to receiving your emails.

This is in your best interest, as less SPAM complaints means better deliverability, and happier customers only receiving the emails they want.

Engage includes a pretty comprehensive unsubscribe system, that makes it easy for your customers and team to handle unsubscribing. The unsubscribe link sends to your customers a page branded for your store, telling them they've been unsubscribed instantly, like so:

This page will use the locale/language set in your Engage settings or in the email settings - more on localising Engage here.

When sending an email using one of Metorik's included layouts, the unsubscribe link appears hidden at the bottom of the email, like so:

When sending a code your own email or using a custom layout, it's your responsibility to add the unsubscribe link. It's important to add it, as without it, customers may mark your emails as spam, in turn resulting in your emails automatically going to spam and your Engage account being suspended.

You can add it by using the {unsubscribe_link} variable to get the link, like <a href="{unsubscribe_link}">Unsubscribe</a>).
