Double Opt-In
Ask people who sign up to confirm their email address before you email them.
With double opt-in on, someone who signs up through your website isn't subscribed straight away. Quotient sends them a confirmation email, and they're subscribed once they click the button in it. This proves the address belongs to the person who signed up, which keeps typos and fake signups out of your audience and gives you a record of consent.
Turn it on in Email Settings under Double Opt-In.
Who gets a confirmation email
Only people who sign up themselves get one: through a signup form on your website (see the SDK), or an event registration that subscribes them.
People you add yourself never get one. That includes CSV imports, quick add and CRM syncs. You're vouching for those people, so they keep the status you give them.
What changes when it's on
| Status | Double opt-in off | Double opt-in on |
|---|---|---|
| Subscribed | Emailed | Emailed |
| Not subscribed | Emailed | Not emailed |
| Unsubscribed | Not emailed | Not emailed |
With double opt-in on, only Subscribed people get your broadcasts and flow emails. Someone who signs up stays Not subscribed until they click the confirmation email, then becomes Subscribed. The topics they signed up for are saved when they confirm, so a welcome flow for a topic starts once they can be emailed. Before it turns on, Quotient shows how many people will stop getting email. To keep emailing contacts you imported, mark them Subscribed. People who were already Subscribed keep getting email.
Turning double opt-in off doesn't change anyone's status. Quotient shows how many Not subscribed people will start getting email again before it turns off. Turning it back on stops emailing Not subscribed people again.
Signing up again after unsubscribing
If someone unsubscribed and then fills in your signup form again, Quotient sends them a confirmation email instead of ignoring the signup, whether or not double opt-in is on. They're subscribed again once they click it. The email lists the topics they signed up for, and they're opted in to those when they confirm. Anyone can enter any email address into a signup form, so a signup on its own isn't enough to undo someone's unsubscribe.
Someone who's already subscribed and signs up for a topic they opted out of is opted back in, with no email: their address is confirmed, and asking for the topic is their consent to it. For example, if they opted out of your newsletter and then sign up for it again, they get the newsletter.
The confirmation email and page
The email links to a page hosted by Quotient. The person clicks Confirm on that page; opening the link alone doesn't confirm, because some email security tools open every link in an email. Links work for 7 days. After that, the person can sign up again to get a new one.
Under Double Opt-In → Customize you can set:
- Sender: the address confirmation emails come from. Without one, they come
from
no-reply@send.quotientemail.ai. - Email copy: subject, heading, body and button text.
- Page copy: heading, description, button text and the message shown after confirming.
The confirm page has its own logo, accent color and dark mode settings, and the email's button uses the page's accent color.
Limits and billing
If the same form is submitted again with the same details, Quotient sends only one confirmation email per 24 hours. There's no other limit yet on how many confirmation emails one person can get.
Confirmation emails don't count toward your email usage.
