How do you opt-out of double opt-ins?

When double opt-in is enabled, new subscribers receive an email asking them to confirm their subscription. Only after they confirm do they start receiving your newsletters.

Double opt-in protects your sending reputation by ensuring only real, engaged people join your list — it filters out bots, typos, and accidental submissions, and helps prevent spam complaints. It’s on by default.

Who controls it

Double opt-in is part of a channel’s Audience Policies, under that channel’s Settings → Sending emails. It’s set per channel — there’s no organization-wide default to inherit from, so changing it on one channel doesn’t affect any other.

Note

If your account sends through company-level audience sending, this setting doesn’t apply to you — it’s handled automatically instead, and you won’t see the Double Opt-In toggle described here. Ask your organization administrator if you’re not sure which sending model your account uses.

Before you turn it off

Turning off double opt-in means anyone who submits an address — including mistyped or fake ones — joins your list immediately. Consider pairing it with Recipient Validation to protect list quality if you do.
