You sent the wrong account number, an old quote, or a stale invoice total — and now you're hoping your client sees the correction email before they act on the wrong one. Afterword fixes the message itself. One link, always current.
A FAMILIAR PROBLEM
Wrong account number
You send an invoice with the wrong account number.
You follow up: "sorry, ignore the last one."
Their finance team already forwarded the first version.
Venue changed last minute
You send the event details days ahead.
The venue changes the morning of.
Half your guests already left, working off the old address.
Quote got forwarded
You send a price quote to your main contact.
It gets forwarded to their boss for approval.
You revise the number — nobody tells the boss it changed.
With Afterword, there's only ever one version — the current one, at the same link, every time.
