On the Domains page, click the + (plus) icon on a domain's row, type a tag name (or pick an existing one), and press Enter. Tags appear as chips on the domain row and become filters on the Domains and Warming pages. Any string works — campaign names ("Q3-launch"), client codes ("acme"), or plain labels ("outbound", "aged"). Bulk-tag from the Domains page by selecting multiple rows first.
When tags are worth using
If you have more than 5 domains, tags start paying off. Common patterns:
- By client (agencies) —
client-acme,client-beta. Filter by tag to see one client's fleet. - By campaign —
q3-launch,q4-newsletter. Track which domains are running which effort. - By state —
warming,active,paused. Fast way to see what's ready vs. still ramping. - By age —
aged-6mo,aged-12mo. Prioritize the older domains for sensitive campaigns.
You can stack tags — a domain can be tagged both client-acme and aged-6mo.
Where tags show up
Tags appear as chips on each domain row, and there's a Tag filter on two pages:
- Domains page — chips on each row, plus the tag filter to narrow the domain list.
- Warming page — filter warming metrics by tag to see how a specific campaign is performing.
Those are the only two pages with a tag filter — the Email Users and Inbox views don't filter by tag.

Frequently asked questions
How many tags can a domain have?
No limit — but 2-4 is usually enough. Too many tags per row makes the list cluttered.
Are tags shared across mailboxes on the same domain?
Yes — tag a domain and its mailboxes inherit the tag for warming purposes. Handy for filtering by domain purpose on the Warming page.
Can I nest tags?
No, flat only. If you want hierarchy, use prefixes — client-acme, client-beta, campaign-q3-launch, campaign-q4-launch.
Are tags visible to affiliates or sub-accounts?
Tags are scoped per account — they don't cross accounts. Reseller sub-accounts have their own tag namespace.
