Help and support

SendLull holds every email you send for a few minutes, so you can still fix a mistake before it leaves. Write to support@tenhatch.com with any question.

Turn it on for everyone (admins)

1. Sign in to the Microsoft 365 admin center with an admin account.
2. Go to Settings, then Integrated apps, and add SendLull from Microsoft Marketplace (or with the link we sent you).
3. Choose who gets it (everyone, or some people or groups) and accept the permissions. SendLull asks to read and change the message being written, and to run when a new message is opened and when Send is pressed.
4. It can take a while to reach everyone’s Outlook. Each person gets a 2-minute hold and can change it in SendLull’s pane.

SendLull holds mail by itself only when an admin deployed it. Someone who adds it alone gets the settings pane but no hold.

Change your hold time

Open a message, then choose SendLull on the ribbon (in Outlook on the web it may be under Apps). Pick 1 to 10 minutes. You can also hold only messages that go outside your organization, and turn off the short reminder in new messages. Changes are saved at once.

Find or stop a held message

In new Outlook and Outlook on the web, a held message waits in your Drafts folder until it is sent. Open it to change it and press Send again, or delete it so it is never sent. A message you set with Schedule send keeps its own time.

Where it works

• New Outlook for Windows, Outlook on the web and Outlook for Mac, with a Microsoft 365 work or school account.
• Classic Outlook for Windows: SendLull lets mail go straight away there, because a held message cannot be changed after Send. Classic Outlook has its own rule for delaying mail.
• Outlook on phones and tablets: not supported.

A message was not held

• Check that “Hold my outgoing messages” is on in SendLull’s pane.
• With “Only hold messages that go outside my organization” on, messages only to your own domain (and the domains you listed) go out straight away.
• If SendLull could not set the hold, Outlook asked whether to send anyway. If Outlook could not load SendLull at all, it sent the message as normal.
• After the free trial, mail is held only with Pro. The pane shows your plan.

Pro and billing

Every feature is free for 14 days. After that, Pro is $2 a month or $20 a year per person, and an admin can buy seats for everyone at the organization. You pay on Stripe’s page from SendLull’s pane. Refunds within 14 days of a charge, no questions asked. See the terms and the privacy policy.
