Send to 25 people a week instead of 300 at once, so you can actually reply to everyone and engage.
The idea
Most people map out a marketing calendar and send everything in giant batches. It feels productive, and it backfires. Replies pile up faster than you can answer, and the conversations you started die in your inbox. We taught my coaching clients to spread it out instead. Same message, smaller waves.
How to do it
Take the list you were about to blast.
Split it into groups of about 25.
Send to one group a week.
Reply properly to everyone who responds before the next wave goes out.
Before each wave, review the last one (who opened, replied, how it landed) and adjust the message or the audience.
Example
Say you're letting your B-list know about a great local event you'll be at. Don't send it to 300 people at once. Send it to 25 in week one and 25 in week two. You won't get bombarded with replies you're too busy to answer, and the engagement goes deeper.
Sent, Seen, Felt: Before every send, review your last one: what you sent, who clicked and replied, and whether they felt what you meant.
Broadcast Rules: Anything you broadcast must be valuable on its own and fit the relationship; then watch who engages and turn that into one-to-one outreach.
The Four-Week Content Model: Answer one prompt a week (work excitement, personal excitement, an experience, what clients feel) and share it to your A's, some B's and social.
Your Authentic Cadence: Decide how many messages a month you're genuinely comfortable sending someone, then plan your sends within that number.
