Should you put email list subscribers through opt-in purgatory? Or let everyone instantly into marketing heaven? We weigh the tradeoffs of the great single vs double opt-in debate that has raged for ages.
Double opt-in leads to heaven-sent engagement but growth hell. While single opt-in greases sign up friction, it scrapes quality and risks damnation from spam regulators one day. Choose your sacrifice wisely!
What is Double Opt-in?
So what exactly is this double opt-in email sorcery that marketers keep debating about? Let’s break it down.
Confirmation Email Process
With double opt-in, when a visitor signs up for your newsletter or mailing list by entering their email address, they don’t get instantly added. Instead, an automated email is sent to their inbox asking them to confirm that, yes, they did intend to sign up.
This confirmation email usually includes a big bright button or link saying something like “Yes, sign me up!” When the contact clicks on that, they are confirming that they want to subscribe and understand they’ll be getting emails from you. Only then are they fully opted in and added to your list.
It’s like a digital pinky promise – “Are you sure?” “Yes, totally sure!”
Difference from Single Opt-in
So how is this different from a single opt-in? Well with single opt-in, users enter their email and boom – no confirmation needed. The confirmation email is basically like an additional verification round before adding contacts to make extra sure they want in.
Think of it as the email subscription version of “Are you sure you want to permanently delete this file?” level of reassurance. But for inboxes receiving your future emails instead of files getting destroyed forever.
The reason it’s called a “double” opt-in is because users first opt-in by submitting their email address. Then they opt-in again by verifying via the confirmation email. Two opt-ins instead of just one – hence the dramatic sounding name!
Loss of Subscribers and Lower Conversion Rates
So double opt-in gives you a squeaky clean list of contacts who have confirmed they want your emails. But this rigorous filtering method isn’t without casualties. Let’s discuss the subscriber loss and conversions rates you might have to tradeoff.
Dropout Between Signup and Confirmation
Remember how we said double opt-in has an extra hoop for contacts to jump through? Well statistics show that when you make users take an additional step, a portion drop off along the way never to be seen again.
As per research by marketing platform GetResponse, double opt-in sees around 20-30% lower conversion rates versus single opt-in. So if 100 people signed up on your website, almost up to 30 of those leads could fail to confirm the opt-in email and make it to your list.
And we’re talking about folks who clearly had some initial interest in your brand by willingly sharing their inboxes with you in the first place! But even that wasn’t enough motivation for all to click a simple confirmation link.
Forgetting to Confirm
Why do these subscribers vanish into thin air rather than verifying their sign-ups? One key reason is forgetfulness. In a world where the average person has 7+ social media accounts and gets 121 business emails per day, things slip through the cracks.
Even the most interested of contacts can accidentally delete your confirmation email or keep postponing clicking on it until it’s buried under a mountain of unread messages. “I’ll get to it later!” famous last words before that email is lost forever.
Higher Attrition Rates
Besides losing prospects in the confirmation limbo, double opt-in can also indirectly increase unsubscribes once users are on your list.
See, some folks who went through the trouble of confirming are extra committed to your emails, while others likely just clicked without thinking and never cared much in the first place. Over time as the casual signups realize “Wait, why am I getting these again?” it can lead to higher opt-outs.
So in summary – more barriers equals fewer prospects converted initially as subscribers. And those fewer subscribers may quit your emails at faster rates in future. Win some, lose some!
Slower List Growth
So we’ve established that double opt-in leads to some contact loss during the confirmation process. But how does that translate in terms of raw list growth numbers? Let’s analyze the cumulative effects.
Less Email Addresses Captured Initially
Think of your website visitors who sign up as fish and your confirmation email as a net trying to catch them before they swim away. With single opt-in, the net catches every fish that bites the hook. But double opt-in has holes in the net so a number of fish escape and never make it into the boat.
This means every 100 signups might result in 70-80 verified subscribers for example. So you miss out on capturing more emails upfront versus grabbing every address that shows intent.
As per research from email marketing platform MailChimp, almost 61% of leads fail to complete the double opt-in process. Over half never convert into list members – quite a leaky net!
Cumulative Effect Over Time
Now imagine you get 500 interested visitors signing up each month. With single opt-in that would translate into approx 500 subscribers joining your list monthly.
But with double opt-in, it would be only 310 if 61% dropped off. So almost 200 fewer email additions per month. Do this month after month, year over year and you can see how your list will grow at a snail’s pace in comparison.
Just because of that extra confirmation step acting as friction and filtering out a huge chunk of potential contacts from making it aboard. Slowly but surely those leaked fish keep adding up!
So technically your list will still grow. Just at a more sluggish rate which can hinder lead gen efforts depending on your goals.
Increased Friction for Subscribers
We know more work equals more reward. But let’s be honest – making contacts jump through extra hoops to subscribe can rub some folks the wrong way. Here’s how it adds friction from a subscriber perspective.
More Steps to Complete
To join a single opt-in list, visitors only need to spare a few seconds and type in their email addresses. But double opt-in interrupts this quick seamless experience.
Now they need to confirm email receipt, dig it out of the overflowing inboxes, click on links that may or may not work on mobile, sometimes even retype email addresses.
It turns what could have been a 5 second process into a multi-step hassle taking minutes for busy contacts receiving 50+ daily emails already. Not fun for subscribers, even if beneficial for delivering marketers.
Potential to Annoy with Confirmation Emails
And this friction doesn’t end once they finally complete the confirmation ritual. You’ll likely send an email confirming the confirmation that they confirmed their subscription. Because logic.
“Thanks for confirming you wanted to join our list after asking us to confirm if you wanted to join our list and then confirming that!”
Layer on your standard welcome email sequence introducing your brand and that’s a lot of unnecessary inbox clutter a new subscriber didn’t bargain for. Risk annoying newly signed up leads right out the gate with email fatigue.
So in summary – double opt-in gives subscribers extra touches to engage with you. But sometimes less is more when it comes to customer experience. The paradox of choice!
Complexity for Marketers
So far we’ve focused on how double opt-in impacts subscribers. But it also creates additional work for email marketers – especially those without huge teams. Let’s break it down from an operations standpoint.
Additional Emails to Set Up
With double opt-in, you essentially need to build and send two categories of emails:
- Confirmation emails with verification links
- Welcome emails for verified subscribers
Both need visually appealing templates designed, content written, links tracked etc. Nearly doubles the effort around setting up signup workflows.
And these multiple automated messages need to align with your brand style. Maintaining consistency in look between confirmation and welcome series adds more overhead when trying to scale email efforts.
Extra Landing Page Required
Besides juggling more types of emails, you also need the back-end infrastructure. When users click confirmation links, they’ll need to land on a page confirming their subscription is now active.
If you’re DIYing your marketing stack, this entire system requires developer bandwidth. More page routing, error handling and notifications to build. Complexity snowballs fast!
Even using turnkey email platforms, while it sets up double opt-in flows out the box, you still have agency in crafting experiences. So the time spent tweaking and testing doesn’t disappear.
In summary – you GET more from subscribers with double opt-in but also have to GIVE more time, effort and resources to manage it. Classic case of no free lunches!
Legal Risks
Besides business complexities, double opt-in also carries potential compliance risks in certain regions. Let’s explore regulatory scenarios you may need to navigate.
Stricter Regulations in Some Countries
Global email regulations run the spectrum from lax to strict. In the United States, the CAN-SPAM act doesn’t explicitly require permission for sending marketing messages. Single opt-in is fair game.
However some countries take a firmer stance. For example due to GDPR consent requirements, European Union inbox owners need more assurances before joining lists.
And in Germany specifically, despite no official legal mandate, double opt-in has become a de facto standard to avoid potential lawsuits. After various court rulings, marketers consider it the safer path to comply with regional norms.
Record-Keeping Requirements
Besides stricter sign-up requirements, certain regions also impose admin overheads around record retention. For instance GDPR legislation necessitates keeping evidence that users intentionally subscribed.
This means saving subscriber confirmation data including timestamps, IP addresses, verification links etc for years. Bringing rigorous data governance practices to what previously required minimal list management.
Failing to maintain comprehensive audit trails can lead to hefty fines if regional agencies come knocking. Especially if you can’t produce records for each contact proving they willingly signed up.
Options to Mitigate Drawbacks
However, just because double opt-in carries baggage doesn’t mean you must abandon all hope:
Incentivize Confirmation
As we discussed earlier, a share of visitors don’t complete the confirmation process due to forgetfulness or laziness. You can reclaim some by incentivizing signups.
Offer exclusive discounts, content previews or contests during confirmation flow. If what you provide is enticing enough, it motivates subscribers to verify subscriptions to gain access.
Send Reminder Emails
Similarly, set up workflows to automatically email subscribers who haven’t confirmed signups after a couple of days.
Politely remind them to verify by highlighting what they’ll miss out on. Recover more leads who simply needed a friendly nudge to complete opt-in.
Carefully Design Confirmation Flow
Also pay attention to optimizing double opt-in user experience. Ensure confirmation links work smoothly across devices and pages have clear calls-to-action.
The fewer speed bumps during verification, the lower drop-offs. Removing all friction beyond the extra step itself helps minimize leakage.
When Double Opt-in Still Makes Sense
However even after factoring in subscriber loss and legalities, double opt-in can still prove prudent in certain situations:
Established Lists
If you already have a sizable list, switching to double opt-in for new signups can maintain quality. Weed out half-interested folks for better long term engagement.
Compliance-Sensitive Industries
Double opt-in also provides cover for businesses operating in regulated sectors like healthcare, finance etc. Margin of safety helps avoid infractions.
Trading off Volume for Quality
And if your goal is an extremely targeted niche list with loyal followers, confirmed opt-ins get you closer vs single opt-in spam. Assess your priorities.
So in short – evaluate whether lowered conversions and increased friction is worth the credibility gained from double verified subscriptions before deploying it universally.
Key Takeaways
If you made it all the way here, congrats – now you’re a double opt-in expert! 🥳 To recap some top lessons on balancing tradeoffs:
- Double opt-in does wonders for list quality but cripples quantity with lower conversion rates. Prioritize accordingly.
- While subscribers complete extra steps, they engage better. But more inbox clutter risks aggravating them later.
- Marketers have to work harder managing complicated infrastructure and regional regulations. Lean on integrations and caution.
- Though not universally required, double opt-in provides legal cover in regulated industries. Crunch cost-benefits numbers.
- Evaluate if leaked subscribers and slower growth is palatable for credibility gained. Mix methods for different lists.
- With great power comes great responsibility! Determine if heightened compliance burden is worthwhile or single opt-in suffices.
At its core, double opt-in lets you and subscribers pinky promise intentionally. Ensure the resulting tradeoffs align before locking hands and jumping in the lake together!
