What is ESP Matching | Everything You Need to Know

ESP (Email Service Provider) Matching is a feature in email outreach softwares that optimizes your email deliverability by aligning your sender's email provider with your recipient’s email service provider. This means emails sent to Gmail addresses will be sent using Gmail accounts, emails sent to Microsoft accounts will be sent using Microsoft accounts, and so on.

This article provides a step-by-step guide to enabling and configuring ESP Matching.

Why Should You Do ESP Matching?

ESP Matching ensures your emails are sent through the right channels, improving deliverability and building trust with email providers. It helps your cold email campaigns land in the inbox, not the spam folder.

Here are some key benefits of using ESP Matching:

Improved Deliverability

Matching your email service provider (ESP) with your recipient’s reduces the chances of your emails landing in spam. It’s like speaking the same language—your emails are more likely to be trusted and delivered straight to the inbox.

Enhanced Sender Reputation

Using the same ESP as your recipient helps you build credibility over time. This means not just better results now, but also stronger deliverability for future campaigns.

Smarter Targeting

Want to tailor your campaigns to specific email platforms? ESP matching lets you focus on the providers that matter most for your audience, making your campaigns more effective.

How to Enable ESP Matching in Cold Email Campaigns

Step 2: Enable ESP Matching

• Scroll down to the ESP Matching section under campaign settings.

For example, you might want to send emails only to Gmail users and exclude others like Outlook.

Before launching your campaign, it’s important to test if ESP Matching is working as intended:

• Go back to the Campaigns section.
• Open the campaign where ESP Matching is enabled.
• Select Preview and Send Test Email to send a test email to different email addresses.
• Check if emails are being sent using the appropriate sender accounts.

Step 6: Monitor Campaign Performance
