Double Opt In Leads
First of all, we need to know what are double opt in leads? Simply put when someone types in an email address is clicks sign up on a webpage; their information is sent to a subscription service like aweber or getresponse. Then, the service sends the person a confirmation email giving a link to double confirm into the subscription. This ensures that the person did actually want to sign up on this list and it’s not a mistake. A single opt in would just the same thing except without the confirmation email.
90% of spam complaints come from single opt in lists. This obviously makes the double opt in lists very safe for the person using the list and there will be few spam complaints. The disadvantage of the double opt in leads is that they will be a large amount of people that will never opt in at all. Double Opt In Leads are also much more valuable since they are more sorted than the single. Double opt in leads will also sell for more per lead if you plan on selling your list.
It’s the webmaster’s decision ultimately. You can try single opt in leads then go for double opt in leads if you are receiving spam complaints. That’s my strategy. If you are building an enormous list, you probably will want to get double opt in leads, but everyone has their own opinion.
