Some Skyp plans include email warm-up service that sends automated emails to help establish your sender reputation. While essential for deliverability, these messages can clutter your inbox. Here's how to automatically filter them in Gmail.

Creating a Filter to Manage Warm-Up Emails

  1. Open Gmail and click the search bar at the top

  2. Click the Show search options icon (three horizontal lines on the right side of the search bar)

  3. In the Has the words field, enter the warm-up keyword provided by Skyp (you'll find this in your Skyp dashboard or setup email)

  4. Click Create filter

  5. Select these actions:

    • Skip the Inbox (Archive it)

    • Mark as read

    • Never send it to Spam

  6. Check Also apply filter to matching conversations if you want to clean up existing warm-up emails

  7. Click Create filter

Your warm-up emails will now bypass your inbox entirely while still registering engagement signals with email providers. They'll be archived and accessible if you ever need to review them by searching for the keyword.

What is Email Warm-Up?

Email warm-up is the process of gradually increasing your email sending volume and establishing positive engagement patterns with a new or dormant email address. Warm-up services send emails between your address and a network of other addresses, simulating natural email activity with opens, replies, and positive engagement signals.

Why Warm-Up Matters

When you start sending cold emails from a new domain or email address, inbox providers (Gmail, Outlook, etc.) don't yet trust you. Without warm-up:

  • Your emails are more likely to land in spam

  • You risk damaging your sender reputation permanently

  • Email providers may throttle or block your messages

Proper warm-up builds sender reputation gradually, ensuring your actual sales emails reach prospects' inboxes rather than spam folders. For Skyp users, this is critical—even the most personalized, compliant email won't generate meetings if it never gets seen. After you launch campaigns, Skyp will continue to send warmup to maintain sender reputation.
