Introduction
A strong email deliverability stack ensures your emails land in inboxes instead of spam. In 2025, setting one up is easier than ever. This guide walks you through building a complete deliverability stack in just 30 minutes—perfect for beginners launching cold email campaigns.
What Is a Deliverability Stack?
A deliverability stack is a combination of tools and settings that improve your email delivery rate. It typically includes:
-
An email provider
-
A sending tool
-
A warm-up service
-
Proper domain authentication
Together, these elements help your emails bypass spam filters and boost open rates.
Tools You’ll Need
-
Email Provider: Google Workspace or Zoho Mail ($6–$12/month)
-
Sending Tool: Instantly or Woodpecker ($37–$40/month)
-
Warm-Up Tool: Warmbox or Mailwarm ($15–$29/month)
-
Domain: Purchased from providers like GoDaddy (~$12/year)
Estimated cost: Around $70/month for a solid entry-level stack.
