What is “reply bumping” and when is it effective?

Reply bumping means sending a very short follow-up message designed to move the thread back to the top of the recipient's inbox.

Typical bump messages:

• Any thoughts on this?
• Wanted to bump this up in your inbox
• Just following up
• Did you get a chance to review?

When bumping can work:

• Prospect showed previous engagement (opened, clicked)
• After a single well-crafted message that may have been missed
• When used sparingly (one bump, not multiple)
• For high-value prospects where persistence is expected

When bumping backfires:

• Multiple bumps in succession (feels desperate)
• After several already-ignored messages
• To prospects who never engaged at all
• As a substitute for valuable follow-up content

Better alternative: Instead of pure bumps, add something minimal but useful. Reference news, share a quick insight, or offer a different angle. Even brief messages should provide a reason to respond.

Bumping is a tool for occasional use, not a strategy. Knocking twice is polite. Pounding on the door is not.
