by JUDAS PHI GATES · CEO Maestros Millonarios
Short, sharp, and built for pipeline. Here are the 22 highest-impact tips from the original guide—condensed into a practical checklist you can run this quarter.
The 22-Point Checklist
-
Set SMART, sales-tied goals Define measurable outcomes (meetings, qualified replies, revenue influence). Clear goals correlate with dramatically higher success.
-
Lock your ICP and personas Narrow firmographics and roles; tailor value props to each persona’s pain.
-
Build targeted, ethical lists Prioritize fit over volume. No mass scraping; source contacts that actually match your ICP.
-
Verify & clean continuously Run verification, remove bounces/unsubs/inactive. Keep bounces <3% to protect reputation.
-
Segment deeply By industry, role, size, geography, or triggers (funding, hiring). Segmentation can drive outsized revenue gains.
-
Personalize beyond the name Reference company context, initiatives, or recent news. True relevance fuels replies and clicks.
-
Authenticate your domain Configure SPF, DKIM, DMARC. Non-negotiable for inbox placement.
-
Use a dedicated, warmed sending domain Ramp volume gradually; don’t jump from 0 to 1,000. Warmth > spikes.
-
Protect sender reputation Throttle sends steadily, honor unsubscribes fast, monitor complaints.
-
Test inbox placement & watch blacklists Use seeds to spot Spam/Promotions issues; remediate early.
-
Write 6–10-word subject lines Add a number or smart personalization/question to lift opens.
-
Craft the preview text on purpose Make line one expand the subject’s promise; don’t waste it on “Hope you’re well…”
-
Keep the body tight (50–150 words) Skimmable lines, bullets where helpful. One email = one idea.
-
Lead with their world; deliver value first Apply an 80/20 value rule: insight, data point, or quick win before your ask.
-
Drop one line of social proof A concise, outcome-focused mini case (“Cut onboarding 30% in 90 days”) beats feature lists.
-
One clear CTA, zero friction Ask for a short call/demo, tie it to value, include two time options or a scheduler link.
-
Offer a polite “not now” / opt-out Earn trust and reduce spam complaints; always make declining easy.
-
Run 4–7-touch sequences Vary angles across 2–4 weeks; many conversions happen after multiple touches.
-
Time sends thoughtfully Favor mornings and mid-week; respect the prospect’s time zone.
-
Go multichannel Layer LinkedIn touchpoints and occasional calls between emails to lift contact rates.
-
A/B test one variable at a time Subject, opening line, CTA, or send time. Small wins compound; subject tests can materially raise open rates.
-
Measure and audit, then codify Track opens, replies, positive replies, meetings, bounce/spam/unsub. Run monthly mini-audits, update your playbook and suppression list, retire weak assets.
