Double Opt-in: Preventing 'My Newsletter Isn't Arriving'

Thank you so much
for opening this article 😊

A mechanism you should know before starting your newsletter

When you start a newsletter,
you tend to focus on "how to attract subscribers"
and "what to write."

But before that,
knowing the mechanism to protect the "quality" of your subscriber list
will make things easier later on.

That is what I will introduce this time:
"Double Opt-in."

What is double opt-in?

Double opt-in refers to
a "two-step verification" for newsletter registration.

With standard newsletter registration,
you enter your email address in a form
and press the submit button to finish.
This is called "single opt-in."

On the other hand, with double opt-in,
a confirmation email is sent after registration.

The registration is only completed
once the link in that email is clicked.

In other words, it confirms the intention to "want to register"
twice.

The benefit is an increase in "list quality"

Double opt-in has
three major benefits.

Only those who truly want to read remain

Only those who click the confirmation link
are added to the list.

This means that "people who signed up on a whim" or
"people who signed up by mistake"
are naturally filtered out.

As a result, only those who truly want to receive emails
will remain on your list.

Prevents invalid addresses

With single opt-in,
input errors or non-existent addresses
are registered as they are.

Not only does this lead to situations where "I registered but the email didn't arrive,"
but continuing to send emails to non-existent addresses
can cause the sender's reputation to drop.

With double opt-in,
only those who receive the confirmation email
are registered,
so this problem can be prevented.

Higher quality of readers

Readers who go through the trouble of
completing the two-step process
are those who are truly interested.

Open rates and click-through rates
will naturally be higher.

If you are worried that
"my newsletter open rate is low,"
there are cases where
many people are not even receiving it
in the first place.
The quality of your list is directly linked to your results.

Know the disadvantages too

Of course, it's not all good news.

Higher barrier to registration

Because there is the extra step of
clicking the link in the confirmation email,
some people will drop off along the way.

"I thought I registered, but
I missed the confirmation email"
is a case that actually happens.

Fewer list numbers

Compared to single opt-in,
the final number of subscribers
tends to be lower.

However, this is a "healthy reduction."

There is no point in
padding your list with invalid addresses.
It is better in the long run
to have only those who truly want to read it remain.

A mechanism that can be used even with free tools

You might have the image that
double opt-in is only available in
high-end paid tools,
but that is actually not the case.

The tool I use,
Systeme.io
, also supports double opt-in.

Moreover, since you can toggle it ON/OFF
for each form,
you can use it differently depending on your needs.

You can also customize the text
of the confirmation email,
so you can send instructions tailored to your readers.

It is great to be able to improve
the quality of your email delivery
with a tool you can start using for free.

One thing to be careful about

When implementing double opt-in,
the thing you need to be careful about is
the case where "the confirmation email itself doesn't arrive."

If the confirmation email goes to the spam folder
or is rejected,
the reader cannot complete the registration.

As a countermeasure,
it is effective to add a note
near the registration form saying,
"If you do not receive the confirmation email,
please check your spam folder."

It is a small effort,
but this alone can significantly change
the registration completion rate.

Summary

Double opt-in is a mechanism
to ensure your newsletter list consists only of
"people who really want to read it."

The number of registrations will decrease slightly,
but the quality of the list will improve accordingly.

Since this is a foundational setting
for building a newsletter system,
it is worth knowing
before you start sending.

😊 Today's mini-question
(Please let me know in the comments section!)

When you register for a newsletter,
do you receive the confirmation email?

Just choosing one of A, B, or C is fine!
Even just a single word would make me incredibly happy!

If you could quickly let me know in the comments section,
it will be a hint for creating the next article!
