Cold Email Follow-Up Sequencing Advice/Tips/Guides?

Here's a checklist I have for creating follow-up sequences:

1. 1Sending pattern: Send 4–5 emails over 10–12 days. Don't spam daily.
2. 2Each follow-up should add value: Don't just say "bumping this." Try to share something to add to the conversation. You can share a cool insight or ask a different question.
3. 3Keep them short: Under 60 words is ideal.
4. 4Use a soft CTA: No pressure, just a gentle nudge or something that starts a conversation.
