Know Who
Not to Email
Good outbound isn't just about finding prospects—it's about knowing who should not be contacted again. Galactic Mails provides automated opt-out suppression and manual exclusion controls to keep unsubscribed contacts and existing customers out of future campaigns.
Your Outreach List Needs an Off Switch
A prospect database is never static. Leads ask to stop receiving messages, opt out, or convert into active paying clients. Without suppression, those addresses can accidentally resurface when uploading fresh CSV files.
Galactic Mails acts as institutional memory for your outreach. Once an address enters your skip list, future campaign imports automatically suppress that contact from dispatch.
Automatic Unsubscribe Recording
When a recipient clicks the unsubscribe link, their email is instantly committed to your account's skip list. Subsequent campaigns across all connected accounts will automatically filter them out.
Custom Exclusions & Customers
Not every exclusion arrives via an unsubscribe link. Manually add paying clients, partners, competitors, or internal employee domains so cold outreach never targets them by mistake:
Skip Lists vs. Email Verification
Hygiene and suppression solve two completely different problems in an outbound stack:
"Is this email address suitable for sending?"
Evaluates technical status, syntax, MX records, and bounce risk before dispatch.
"Should we be sending to this person?"
Enforces relationship rules, opt-out requests, and policy compliance even if an address is 100% valid.

Suppression & Skip List FAQ
What is an email skip list?
An email skip list (also known as a suppression list or do-not-contact list) stores email addresses that must be excluded from all future outbound campaigns across your account.
What happens when someone unsubscribes?
Their address is instantly recorded in your account's skip list and automatically suppressed from all subsequent campaigns, even if re-uploaded in future CSV files.
Can I manually add existing customers to the skip list?
Yes. You can manually insert specific addresses or domains to ensure current clients, partners, and internal staff never receive cold outreach messages.
Is a skip list shared across all my connected sending mailboxes?
Yes. The suppression list applies globally across your entire account, covering Automated Drip Campaigns, Bulk Campaigns, and Single-Launch workflows.
