Co-registration is Implicit single opt-in & occurs when a consumer fills out a form, e.g. in order to download content or register for an event. Sometimes this happens when a consumer registers for something on a third-party site, and the site shares the email addresses with sponsors. In either case, the website’s privacy policy must state that performing this action automatically opts the user into email marketing. This is a commonly used method in the B2B marketing sector – It has some advantages, including:
- Requires the least amount of effort on the part of both the company and the customer.
- There’s no place for a subscriber to drop the ball, which can happen when the customer is required to “confirm” their opt-in.
- Quickly leads to a big list.
The problem is that the subscriber doesn’t connect registering for something to your subsequent email. If a subscriber forgets that he opted in, or doesn’t realize he has opted in, the risk is high that he’ll mark your email as spam. This is particularly true when too much time has elapsed between subscriber sign up and your first communication.
How to Engage
- Welcome Emails. When a new subscriber enters his information, an immediate auto-response email thanks and welcomes the subscriber. This email includes a customized message that tells him what to expect in future emails, and when to expect them. It’s courteous, and it also serves as a good way to begin earning the trust of your subscribers while setting proactive expectations.
- Explicit Opt-In. Requires the user to voluntarily (and explicitly) sign up for email marketing. Often, this takes the form an explicit sign-up for updates, or a checkbox on a registration page that reads something like, “I want to receive news and updates.”
- Confirmed or Double Opt-In. After the subscriber enters their email, the post-subscribe thank-you page may alert him to look for an email. Once he receives that email, he needs to click on a link or button to confirm the subscription. This separates the committed from the simply impulsive; those who click on the link really want to receive your emails – though there is always a risk that an interested subscriber will get distracted before she can click “confirm” in the follow-up email, or, worse, that your email will get lost or filtered. As a result, you may lose interested subscribers.
