Opt-in, Confirmed opt-in and Doble Opt-in Lists

The way you add contacts to your lists largely determines the results obtained on your email marketing campaigns. Whatever method you use to get your contacts, remember to always have their consent.

Contact lists can be classified according to the interaction taken by the contacts in the subscription process:

Opt-out lists

Contacts have been added to the list from publicly available data sources like business cards, websites, etc.. or by pre-selected options usually in a form like "Yes, I want to receive news in my email". For those contacts, you do not have the express authorization of the user or the consent was obtained without being very conscious of it. You should avoid getting contacts in this way for several reasons:

• the regulations in force specifies to always have the consent of the user to send them commercial communications
• if a contact does not know why he is receiving your email, he will most likely not read it, unsubscribe from your list, or worse, report your email as spam

Single opt-in lists

Subscribers give their consent in a form, but no further check is performed.

Even they are not as "bad" as opt-out lists, since no further confirmation is requested, anyone can include the email from a friend, family or relative, who has never heard from you before and thus, who is probably not interested in your communications.

Confirmed opt-in lists

The contact signed up by means of a form, thereby giving his consent at the same time. Additionally, he receives a Thank-you message like "Thanks for subscribing to this list" which includes a link to unsubscribe.

This option is better than the previous one but cannot prevent the registration of email addresses of third parties that never heard of you.

Double Opt-in Lists

Lists where contact signed up by means of a form, and who receives an email with a link to confirm the subscription to the list.

With this method, those contacts who would not click on the confirmation link are not added to the list. This may seem like a big deal, but do you think a contact is really interested in your product if he was not able to click on a link? Would he really read your emails?

This is the reason why double opt-in lists are the best choice to guarantee quality new contacts to your lists.

Acrelia News always use double opt-in forms to ensure that you get quality new subscribers for your lists.
