What is Double opt-in or Single opt-in in List Building
First this is about building a list where you can use follow-up emails to market to them. You advertise something or your blog with a squeeze page. It can even be a form on your blog they fill out.
It is also about what takes place after they fill out the form. All you of you have gone through the process at some time.
A single optin is where you fill out a form with your name and email and you are signed up to an email list.
A double optin is where you fill out a form with your name and email and then you have to click on a link sent to you in an email to confirm that you want on the list.
Even though people argue against it I have always used double optin sign ups.
I tested both type list single optin and double optin several years ago and what I learned convinced me to use double optin.
Yes, you get less signups with double optin but it is worth it and here is why.
I set up 2 list on the same autoresponder for the same free eBook as a reason to signup.
It was not long until the Single optin was over twice as big as the double optin. So I lost at least 50% of signups using double optin.
The big difference showed when I mailed to the list. The double optin had a little over 1000 members and the single had 2500+. I used the exact same subjects, emails and autoresponder.
On the double optin I got a very high open rate (how many actually opened the emails. and conversion rate (where they buy something) on the emails.
On the single optin and I got a very low open rate and conversions were also low.
So in the long run the double optin got more emails read and more conversions with a smaller list.
Every since then I have done double optins. They work for a reason
One last thing. On a single optin anyone can signup anybody up they want to a list. All they have to do is put in a name and email. So if you are mad at someone you can sign them up to all kinds of things. That leaves you open for spam complaints. Even if you capture the IP when they signup it does not keep you from getting spam complaints.
Not this kind of Spam
If it is a double optin where they had to click a link in their own email it takes all that off the table. You may still get a few but they are not even looked at as spam because you used double optin.
I know there a lot of good arguments for both but bottom line for me is that over and over I have had a better open rate and made more money off of double optin list.
Which one do you use.
