What You'll Learn
Good email content isn’t enough. How you send emails — how often, how many, and how you start — matters just as much for inbox placement. This lesson explores the best practices for sending frequency, volume, and warm-up to keep your emails out of spam.
📖 Best Practices for Email Sending (Frequency, Volume, Warm-up)

Sending Frequency
- Consistency is key → ISPs (like Gmail, Outlook) notice if you send in a predictable pattern.
- Don’t send too rarely (cold domains lose reputation) or too often (subscribers get annoyed).
- Match frequency with audience expectations.
- Daily: Newsletters, deals
- Weekly: Updates, blogs
- Monthly: Reports, summaries
Spam trigger: Sudden spikes after long silence.
Sending Volume
- ISPs monitor how many emails you send per day/hour.
- Sending too much too fast from a new domain/IP looks suspicious.
- Gradual scaling builds trust with ISPs.
- Use throttling (spread large campaigns across hours/days).
Example: Instead of blasting 100,000 emails at once, send 10,000/hour.
Warm-up Process
- New domains/IPs have no reputation — ISPs don’t trust them yet.
- Warm-up = start small, then gradually increase volume.
- Example warm-up schedule:
- Day 1: 50 emails
- Day 2: 200 emails
- Day 7: 1,000 emails
- Day 30: 10,000+ emails
- Warm-up works best if emails go to engaged recipients (those who open, reply, click).
Other Key Practices
- Engagement matters → Gmail cares more about open/reply rates than raw volume.
- Remove inactive users → Keep lists clean.
- Segment audiences → Send relevant content, not “spray & pray.”
- Monitor bounces → High bounce rate kills reputation.
🥋 Sensei Tip
“Think of ISPs like bouncers at a nightclub. If you suddenly show up with a huge crowd they don’t know, they’ll block you. But if you slowly bring trusted friends inside, one group at a time, you’ll build a reputation — and soon, the door opens automatically.”
