Simple sponsor tracking for newsletters

Never promise the same sponsor spot twice.

See every upcoming issue in one place. Reserve a spot while a sponsor decides, confirm it when they say yes, and automatically free it again if they do not.

Issue 185 is already reserved, so nobody else can take it. If the sponsor does not confirm in time, the issue becomes available again automatically.

No more double-booking.

Everyone sees the same sponsor status, so two people cannot accidentally sell the same issue.

No forgotten “maybes.”

Reserve a spot while a sponsor decides. If they do not confirm in time, it opens up again automatically.

Always know what happens next.

Move each sponsor from available to reserved, booked, ready, and published in a clear order.

How it works

From open spot to published issue in five simple steps.

SlotHold keeps each sponsor spot moving in the right order, so your team always knows what is available and what is already taken.
