Email verifier: Deliverability Statuses

In lemlist, every lead’s email comes with a status tag that shows whether it’s safe to send messages. Knowing what each status means helps you improve your email deliverability and campaign performance.

There are four possible statuses: Deliverable, Risky, Unknown, and Undeliverable. Each gives you key insights into the quality of the email address.

1
Deliverable

“Deliverable” means the email address is valid, and messages will likely reach the inbox. This is the safest category for sending emails.

2
Risky

“Risky” emails could lead to bounces or low engagement. This category includes:

  • Accept All: The mailbox accepts any email, but it may not be valid.
  • Full Mailbox: The mailbox is full and can’t receive new messages.
  • Disposable: A temporary email address that may no longer exist.

Be careful when sending to risky addresses, as they can harm your deliverability.

3
Undeliverable

“Undeliverable” means the email address is invalid. This can happen if:

  • The address is entered incorrectly.
  • The address simply doesn’t exist.

Avoid sending to undeliverable addresses since they will bounce.

4
Unknown

If the status is “Unknown,” there isn’t enough information to confirm if the email is valid or not. Sending to these addresses is a risk.

By checking these email statuses in your lead list, you can filter out risky and undeliverable addresses. This helps you focus on the most reliable emails, boosting your campaign’s performance.
