After sending an initial cold email proposal, how should I maintain momentum with the client—should I keep sending new proposals for each follow‑up, or establish a streamlined process for ongoing collaboration and upselling?
You should aim for a retainer or monthly subscription instead of sending a new proposal every time. Bundle your deliverables into a recurring package—e.g., X systems per month, a weekly strategy call, daily Slack availability, etc. You can also charge hourly, but a retainer minimizes friction on follow‑up projects and keeps the relationship smooth. Include any legal terms like IP, NDA, or unsolicitation clauses in the agreement.
