Why Enable Double Opt-In on Your Forms?

1. The Hidden Risk: Spam Traps in Your Forms

In the world of email marketing, maintaining a good sender reputation is crucial. One of the main threats to this reputation is spam traps. These email addresses, used by organizations that monitor bulk email sending, do not belong to real users. Instead, they are designed to detect questionable practices, poorly configured automations, or a lack of validation in signup forms.

When one of these traps enters your audience, either through uncontrolled sends or unprotected forms, there is a risk your IP addresses will be blacklisted. This can severely impact your deliverability, causing your emails to end up in spam folders or not be delivered at all.

Although this risk mainly affects email, validating the subscription is also important in forms with SMS: it helps avoid mistyped phone numbers, reduces unwanted signups and gives clearer proof that the contact accepted communications through that channel.

2. Why Is Double Opt-In Important?

Double opt-in is a highly recommended practice to ensure that only genuinely interested users subscribe to your audiences. This method involves a two-step verification process:

1. A user subscribes through your form, by email, SMS or both channels.
2. They receive a confirmation message by email and/or SMS, depending on the channels configured in the form.
3. Only when they confirm the corresponding channel is that channel considered valid.

This process automatically filters out malicious entries, fake addresses, wrong phone numbers and bots, helping maintain high-quality audiences. The result is higher open rates, better deliverability and fewer issues with anti-spam services.

In forms with email and SMS, confirmation is separated by channel. A contact can confirm email and still have SMS pending, or confirm SMS before email. This makes it possible to keep independent proof of consent for each type of communication.

3. Mandatory Double Opt-In Activation on Easymailing

To protect all users' reputations and uphold high-quality standards in audiences, Easymailing applies double opt-in to subscription forms according to the channel and the account's compliance rules.

• In forms with email, email double opt-in is enabled by default.
• In forms with SMS, SMS double opt-in can be enabled independently. If the account has a compliance rule that requires it, it will appear enabled and cannot be disabled.
• The confirmation messages for email and SMS are managed separately.
• In exceptional cases, such as internal or private forms, single opt-in may be requested by contacting technical support.

4. How to Configure Double Opt-In on Your Forms?

Activating this feature is simple via the Easymailing form editor:

1 Open the form you wish to edit.

2 Go to the configuration section.

3 Enable or review the "Double opt-in Email" option if the form uses email.

4 Enable or review the "Double opt-in SMS" option if the form uses SMS.

5 Customize the corresponding confirmation message if desired, or use the default one.

5. A Measure to Protect Your Reputation and Results

Using double opt-in helps preserve the health of Easymailing's sending ecosystem. For email, it protects deliverability. For SMS, it helps confirm that the phone number belongs to a person who accepted communications. In both cases, it reduces blocks, bounces, fake signups and provider issues.

Remember: a quality audience is not defined only by its size, but by the real engagement of its members and by valid consent for each channel.
