    • Mark it as read

    • Move it to the specified folder (create a "Warm-Up" folder or select Deleted Items)

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.

Skyp will continue email warm up while your campaigns run as part of the platform, to ensure deliverability stays good.
