10 Best Single Opt-In Email Marketing Service Providers

Email marketing is one of the best ways to engage with visitors as well as for getting more subscribers and customers. Here, we have featured 10 Best Single Opt-in Email Marketing Service Providers.

As you would already know, there are two opt-in methods that your visitors can use for subscribing to your emails:

  • Single Opt-in
  • Double Opt-in

Each of these methods has its own implications for list growth, conversions, subscriber engagement, & more.

Here, we have shared valuable insights about both single opt-in as well as double opt-in methods so that you can make out the difference between the two and make an informed decision on which one will get you better conversions.

Single Opt-In Email Marketing Service Providers

So, let’s get started with it.

Single vs. Double Opt-In

In a nutshell, single opt-in means that your subscribers get signed up when they submit their email addresses. However, in the case of double opt-in, subscribers have to confirm signing up for your email list.

Let’s get to know the difference between single opt-in vs. double opt-in in detail.

In single opt-in, users have to complete “one” opt-in action for receiving emails from your company.

It means that subscribers sign up using a subscription form and are immediately added to your email list. They do not need any further confirmation for getting your emails.

So, they start getting your emails right away.

Here’s an example of a single opt-in in action.

Suppose a box pops up when you visit a website and it asks you to sign up for the mailing list for getting updates in the future. That’s an opt-in prompt that you have to fill it and submit. That’s all.

You will instantly receive a welcome email and start receiving the daily/weekly/monthly emails that the company sends out.

This is a single opt-in as it required you to complete one action for receiving emails.

Here are some key features of Single Opt-In for you:

  • It allows you to build a large list quickly
  • There is no contact ‘leakage’
  • There is potential for unengaged subscribers
  • More time needed for list maintenance
  • Higher risk of spam complaints

However, a Double Opt-In is somewhat different from Single Opt-In.

In double opt-in subscribers have to sign up via your subscription form, and they get an email with a link that they need to click for confirmation that they want to get emails from you. It’s called the confirmation email.

So, in the case of double opt-in subscribers must confirm; otherwise, they will not get your emails.

It means that in double opt-in, there’s a confirmation step to the process. Here, you get a “confirm your opt-in” email. You need to click the verification link, and then you’ll receive the welcome email and start getting the mailing list updates.

Essentially, the difference between the single opt-in vs. double opt-in is the “second” action. In double opt-in, you have to confirm your enrollment in the mailing list for receiving the emails from the company.

Here are some key features of Double Opt-In for you:

  • ‘Cleaner’ list
  • Active & engaged database
  • Slower list of growth
  • There is potential for contact ‘leakage’

Benefits of Single Opt-In

Single Opt-In offers a considerable benefit in the sense that when a subscriber signs up, they’re immediately on the list. So, with a single opt-in, you can grow your list fast. You’re able to connect with new subscribers easily.

Single Opt-In offers a win-win scenario for both you and them. You benefit as you get quick results, and your visitors get the instant gratification of getting to your list. There’s no worry about “unconfirmed” subscribers. Everyone who signs up is on your list.

Benefits of Double Opt-In

The biggest highlight of the double-opt-in method is that you get a “more” engaged list. In double opt-in, subscribers need to confirm, so the people you get on your list wanted to sign up.

It means that the people you get on your list will be more responsive to your emails. They are “more” likely to open and click your emails. With double opt-in, the subscriber engagement is on a higher level, which is a “huge” plus for your business.

The advantage with confirmed subscribers is that they do not report your emails as spam. In fact, too many spam reports can damage your sender reputation and can affect email deliverability.

This should be avoided at every cost as with poor sender reputation, and your emails never reach subscribers at all.

However, with double opt-in, there is no such problem as subscribers are already engaged, thereby enhancing your sender reputation resulting in higher deliverability.

Another good thing with double opt-in is that it keeps your email list clean. Spammers can sometimes target single opt-in email lists, but this is not the case with a double opt-in method.

With double opt-in, you get more accurate subscriber data as all list members are confirmed. You don’t need to email people who aren’t interested. It’s a list that has been built on quality rather than quantity. So, these are the main benefits of a double opt-in method.

How do countries regulate subscriptions?

Each country has formulated its own laws against spam. For example, in the USA, there is the CAN-SPAM Act. To follow it, the single opt-in is enough. However, in the EU, a new GDPR policy has been implemented, which requires that a user needs to provide a verifiable consent for receiving emails from a company.

The trend nowadays, with most email marketers, is that the double opt-in is seen as a sign of “clear” consent. Having said this, it’s not the case that it is absolutely required. However, the double opt-in does make it easier to prove sender legitimacy.

When you choose between the two options, you have to consider the “specifics” of your business, its location, and the laws of the country of your audience.

Moreover, you need to consider the quality of your mailing lists that you get with double or single opt-in. Eventually, you should send emails to the audience who agreed to receive them.

Now that you have a good idea about Single vs. Double-Opt-In, it’s time to share with you the list of 10 Best Single Opt-In Email Marketing Service Providers.
