The Coalition is email infrastructure on themailcoalition.org, built for joint campaigns and partnerships between independent organizations.
Coalitions form and dissolve. Your email shouldn't have to follow that same messy path.
A joint address for campaign correspondence, staffed by all partner orgs.
Partner organizations keep their own domains and mail, unaffected.
When a coalition ends, access and inbox history transfer or archive cleanly.
"Three organizations, one campaign inbox, zero confusion about who's replying to what."
"When our joint campaign wrapped, archiving the shared inbox took ten minutes."
"Each partner org kept full control of their own domain the whole time."
No, partner organizations keep their existing domains and mail entirely separate — this is only for the shared coalition address.
The shared inbox can be archived and exported, or access simply revoked, with no impact on partner orgs' own systems.
