What the Mailchimp Integration Does
The Email Verifier by EcomTech Mailchimp integration connects our industry-leading email verifier directly to your Mailchimp account, giving you the power to verify every subscriber email in your audiences. The integration works at two levels: proactively verifying new subscriber emails as they sign up through your forms and landing pages, and reactively cleaning your existing audiences by verifying all subscriber emails in bulk. Every email address is run through our full 7-layer verification engine including syntax validation, domain checks, MX record analysis, SMTP mailbox verification, disposable email detection, catch-all detection, and spam trap identification.
Mailchimp charges based on audience size, and industry data shows that 15-25% of a typical email list consists of invalid or undeliverable addresses. These invalid addresses cost you money every month through inflated subscriber counts, and they damage your campaigns by increasing bounce rates and triggering spam filters. Our integration identifies and tags these addresses so you can remove them or archive them, directly reducing your Mailchimp bill while simultaneously improving your campaign deliverability and engagement metrics. The integration preserves your existing audience organization, groups, and tags while adding verification status tags that you can use for segmentation and automation. Customers typically see a 15-30% improvement in open rates and a 50-80% reduction in bounce rates after their first audience cleaning.
Step-by-Step Setup Guide
Connect Your Mailchimp Account
Log into your Email Verifier by EcomTech dashboard, navigate to Integrations, and click Connect Mailchimp. You will be redirected to Mailchimp to authorize the connection via OAuth. Grant the requested permissions which allow our integration to read your audiences and update subscriber tags. The connection is secure, encrypted, and can be revoked at any time from either your Mailchimp or EV dashboard.
Select Audiences to Verify
After connecting, the integration displays all your Mailchimp audiences with subscriber counts. Select the audiences you want to verify. You can verify all audiences at once or start with your primary audience. Each audience is processed independently, and you can add or remove audiences from verification at any time through the integration settings.
Configure Verification Tags
Customize the tags applied to subscribers based on their verification status. By default, the integration uses EV-Valid, EV-Invalid, EV-Risky, and EV-Unknown tags. You can rename these to match your existing tag naming convention. These tags allow you to create segments in Mailchimp that include or exclude subscribers based on their email verification status.
Start Bulk Audience Verification
Click Verify Audience to start the bulk verification process. The integration exports subscriber emails, verifies each one through our engine, and applies the appropriate tags. Progress is displayed in real-time with estimated completion time. For a typical audience of 50,000 subscribers, the process takes approximately 30 minutes. You receive an email summary when verification is complete.
Enable Auto-Verification for New Subscribers
Turn on auto-verification to check every new subscriber email as they join your audiences. The integration monitors your audiences via webhooks and verifies new subscriber emails within seconds of signup. Invalid and disposable emails are tagged immediately, allowing you to set up Mailchimp automation rules that handle them automatically, such as sending a confirmation request or unsubscribing the address.
Create Verified Subscriber Segments
In Mailchimp, create segments based on the verification tags. Build a Valid Subscribers segment that includes only contacts tagged as EV-Valid and use this segment as the default audience for all your campaigns. Create a separate segment for invalid contacts and review them periodically. Set up a monthly recurring verification job to catch emails that have become invalid since the last check.
