Add your ReplyBump address as a BCC when you send a proposal.
Your personal ReplyBump address appears here once you sign up.
Start a new message with your proposal.
In Options, turn on “Bcc” so the field shows.
Add your-address@in.replybump.com to Bcc and save it as a contact named “ReplyBump”.
Send. ReplyBump confirms within a minute.
Tip: You can also create a rule in Settings → Mail → Rules that uses “Forward to” your-address@in.replybump.com for messages you send with “proposal” in the subject.
