Questions and answers

How many SDRs does a $5M agency need?

Usually 1-2 SDRs plus a senior closer, supported by a strong list-building process. Throwing more SDRs at bad lists doesn't fix the input problem.

Should agencies use AI personalization?

For first-line personalization, yes — but only when it's grounded in real data (a recent post, a specific page on their site). Generic AI compliments hurt more than they help.

What close rate is realistic?

From cold contact to closed: 1-3% on broad lists, 5-10% on signal-based lists with narrow ICP. Anyone quoting higher is either lying or counting referrals.
