The City of Hamilton transitioned to a new official email domain in February, and the transition period is now coming to a close.

City email addresses have changed from:
@ci.hamilton.tx.us → @cityhamiltontx.gov

Update Your Contacts Now

Residents, businesses, and partner agencies should update their records to ensure they are using the new @cityhamiltontx.gov email addresses for all City communications.

What to Expect

• All City staff are now using the new email domain
• Messages sent to @ci.hamilton.tx.us may soon no longer be received
• Future communications will only come from @cityhamiltontx.gov

Why the Change?

This update improves communication reliability, aligns with modern government standards, and strengthens the security of City email systems.

No Changes to Services

City services, phone numbers, and office locations remain the same—only the email domain has changed.

If you have questions or need assistance, please contact City Hall.
