Confirmed Opt-in improves campaign results! Check out these stats now!


About three months ago, we were trying to convince you that confirmed opt-in option is much more effective than the unconfirmed opt-in when adding qualified subscribers to your lists. We gave you several important reasons to validate our point of view.

If the last blog post didn’t convince you, we hope the results of our latest analysis will help you understand how well confirmed opt-in works for real-life GetResponse customers, and put all serious arguments to rest.

Now, onto the study: we analyzed over 700M messages sent from GetResponse Pro accounts between August 1st and November 1st 2009, and compared certain “success” factors for confirmed opt-in and unconfirmed opt-in users. We thought we’d find improvements with confirmed opt-in, but the results amazed even us!

According to the analysis, messages sent from accounts using confirmed opt-in returned 71% higher Open Rates and 66% higher Click Rates than unconfirmed opt-in account messages. That’s close to “double” the good results!

That’s not all! The number of “undeliverable” messages in accounts where users applied confirmed opt-in had 75% fewer bounces than accounts where users chose the unconfirmed opt-in option. Moreover, in confirmed opt-in accounts, spam complaints were almost 40% lower!

Based on these stats, just imagine the difference confirmed opt-in could make in the success of your email campaigns. Here are just a few of the advantages of confirmed opt ins:

  • Your list is cleaner as your database includes only confirmed email addresses.
  • Your recipients open your messages more willingly because they chose to subscribe to your list.
  • Usually recipients remember they subscribed and rarely send spam complaints to your email marketing provider (e.g. GetResponse) or your ISP.
  • You get much better click-through ratios, which can lead to higher sales ratios.
  • You gain higher-value customers and fewer “unsubscribes” overall.

All these factors improve your reputation as an email marketer − and your email marketing results!

Finally, please don’t worry that if you use the confirmed opt-in option, you’ll annoy new subscribers. Most appreciate the reminder and the extra “protection” it gives them from unwanted emails. Believe us when we say, your subscribers will be grateful they are only receiving messages they truly want − and you will enjoy all of the above benefits PLUS have higher deliverability rates and a cleaner list. Remember, that’s your “goldmine”!

To be balanced, if you think there are any disadvantages to the confirmed opt-in option, just let us know. We sure couldn’t find any, but would like to hear from you – pro and con!

  • I was disappointed in this post because you didn’t compare the REAL numbers in the unconfirmed vs confirmed optin game.

    Of course confirmed optin gives all these great results. I’ve been using it for years and am happy with it … however I sometimes wonder if single optin would have been better as I would have a much larger list and with good emal copy many of those single optins can be turned into happy subscribers. Those would have been subscribers that I wouldn’t have normally gotten with confirmed optin (they never got the confirmation, they forgot why they subscribed, they never got around to confirming).

    So you didn’t compare the difference in how many MORE subscribers single optin vs double optin would provide. Then the % profitability of the two options would be weighted by the difference in volume (single/unconfirmed optin gives x times more subscribers).

    With single/unconfirmed optin you are getting all those happy double confirmed subscribers plus many more. Of course you also pick up bogus emails, unhappy subscribers, etc.

    Do you have any stats on which option is more profitable, including the list size factor?

  • I’ve got nothing against confirmed opt in, but I think your comparison is fundamentally flawed.

    Of course the response is higher — confirmed opt in has a higher bar for subscription so anyone who goes through the process is going to be more interested from the start. But what you’re leaving out is the fact that the list itself will be much smaller when you require a confirmation (charging $100 to opt in – for example – would have an even higher open and click through rate, but it may not be a great idea since your list will be tiny).

    So while I think it’s a reasonable (but not necessary) practice in many cases, your data isn’t convincing.

    Dear ALL,
    Thank you for your comments. It’s clear to see this topic is quite controversial! We knew there are varying opinions out there and boldly decided to research the issue with our GetResponse users.

    The stats clearly show that confirmed opt in is more efficient than unconfirmed opt in, so we reported the results to you! No spin, no opinions…just real stats based on all our Pro account activity. Reviewing the data, we could come to no other conclusion than that confirmed opt in really can increase campaign results.

    But we know our analysis may not jive with your point of view or experience, so we really appreciate that: 1. You read our blog; 2. You shared them with us. The topic continues even now, in Comment threads and conversations.

    Believe me, we try to grab everyone’s posts and read them very carefully. We discuss and ponder and argue over them…and sometimes it leads to a new blog post. Perhaps we could create a post that shows all of the varying views on the confirmed opt in argument?!

  • I am a long time marketer. Online since 1999 Used all the mail firms. Aweber Getresponse Icontact ConstantContact Ect…. Been boooted over single opt in spma rates from some firms Getresponse included and truly the commentary here is skewed. There is far more monetary value in a single opt in list. The list grows faster and get results way fatser then a double opt in for dollar conversions over lets say 12 month. Yes double opt is better quality but would you rather market to 100 doubles or 800 single opts. In ten years in running this game single was won hands down every time! thanks Joe

    I have a grouping of about 3000 raw email names that will need to opt in. Most of these “Blackberry” users barely pay attention to anything. How do you even set up the initial opt in that will get attention. I’m talking now of people that might opt in but getting them to click anything is like pulling teeth.

  • Just about this whole double opt-in issue, or confirmation of opt-in. I recently had a discussion about this with a very seasoned online marketer and here is a short metaphore:

    If you go to the warm bakery store and you ask the assistant behind the counter for a loaf of whole meal bread, because that is what you want, and the assistant then would ask you, ‘Are you sure? Do you really want that?’

    I mean… seriously folks, when people subscribe, they want your information… now! And not some kind of confirmation email…

    In my opinion… a double opt-in is opting yourself in for loosing or missing out on subscribers 🙂

  • Jonathan Johnson

    good post, but too bad there arent any statistics about the difference of percentage of buyers that land on a single optin squeeze page and a double opt in squeeze page….

    if anyone have more statistics about double/single optin i would like to read it.

  • I definitely would rather use single opt-in with my type of direct response marketing.

    I find some people just forget to hit the confirm subscription link. I was using another service and I had tons of unconfirmed email addresses every day which was just a pain. Since removing that, I have made more money online without a doubt.

    I think when a newbie start email marketing should start with single opt-in, when the list grow then can switch to double opt in. But I believe double opt in is good for long term reputation.

  • If someone has purchased an item from you from ebay, don’t you have the right to email them and ask them, how’s it going with the purchase, and market to them? Why should they have to confirm they want email from me, when they are already my customer? I know I lost a customers contact, because they didn’t double opt in. They bought, received my digital item, and then decided not to opt-in.

    With some many people getting so many emails everyday they do not see the first message to opt in and then never get another message again from you again, I think double opt in sucks! When I want a clean list I just ask my already subscribers to then opt in for something else and when they do I know they are on my serious buyer list.
