How to set up sending double opt-in emails?

InSend has a mechanism for double confirmation of a subscription (double opt-in). This means that after the visitors has entered their email address – for example, in the sign-up form for collecting emails – they will receive a confirmation email in which they must confirm their consent. Then emails will not be sent to all subscribers, but only to those who want them.

Sending opt-in emails

You can send a subscription confirmation email in three cases:

1. After the visitor has entered their email address in sign-up form.

2. After the visitor has entered their email address in the form on your site (implemented by sending the event in InSend).

3. After the visitor has placed an order.

1. Sending opt-in emails after filling out the widget

To send an opt-in emails to a visitor after you have received their email address from the sign-up form, you need to put a check in the web forms settings:

For example, there is a sign-up form with an email field which is tied to an email with a promotional code. Two options are possible:

• If the box is checked – the web form is shown to the visitor. They enter their email address and press the button. They immediately receive a confirmation email. The email with the promotional code is only sent after the visitor confirms their subscription.
• If the box is not checked – the sign-up form is shown when the visitor enters their email address. The email with the promotional code is sent immediately. No opt-in emails are sent.

2. Sending opt-in emails after receiving an event from the website

Let’s say you have your own form for collecting email addresses or registration. You can use InSend to send a confirmation email to all those who have entered an email address via this form.

You need to create an event in InSend. On the button in the form, register its code with the require_opt_in = true parameter. When the visitor clicks the button, the event will go to InSend and cause the email to be sent.

Example of event syntax:

insend("event", "custom", {key: "your_key", require_opt_in:true}, {email:"<a href="mailto:mail@example.net">mail@example.net</a>"});
