# Emails — Marketing Skill for AI Agents

An email sequence is an automated series of messages triggered by an action or a date, where each email does exactly one job and moves toward a single conversion goal. Common flows and lengths: welcome (5-7 emails over 12-14 days), lead nurture (6-8 emails over 2-3 weeks), onboarding (5-7 emails over 14 days), and re-engagement (3-4 emails over 2 weeks). Lead with value before the ask, send the first email immediately, then space early emails 1-2 days apart and later ones 2-4 days apart. Every email follows the same shape — hook, context, value, one CTA, human sign-off — with a clear, specific subject line of 40-60 characters.

## Example

**Prompt:** Create a welcome email sequence for new users who sign up for our project management tool's free trial. The trial is 14 days. We want to get them to their aha moment (creating their first project and inviting a team member).

**Welcome sequence — Email 2 of 6 (Quick Win)**

Send: Day 1-2 after signup
Subject: Get your first result in 10 minutes
Preview: The one setup step that makes everything else click

Hey {{first_name}},

Most people who stall out never finish this one step — so let's knock it out now.

Connect your first project and you'll see your team's work in a single view (this is the moment it clicks for most folks). Takes about 10 minutes.

## FAQ

### How many emails should a welcome sequence have?

Typically 5-7 emails over 12-14 days: welcome and deliver the promised value immediately, a quick win on day 1-2, your story or why on day 3-4, social proof on day 5-6, an objection-handler on day 7-8, a core feature highlight on day 9-11, and a conversion push on day 12-14. Fewer, more relevant emails beat high volume.

### How far apart should automated emails be sent?

Send the first email immediately after the trigger, keep early-sequence emails 1-2 days apart, nurture emails 2-4 days apart, and long-term emails weekly or bi-weekly. Where you can, use behavior triggers (e.g., they completed a setup step) with time-based delays as the fallback. For B2B, avoid weekends and send at the recipient's local time.

### Our open rates dropped. Is it just the subject lines?

Subject lines are one factor, but a sudden drop usually points to sender reputation, list hygiene, or deliverability. Run a re-engagement sequence to clean inactive subscribers (they drag down deliverability), then improve subject lines: keep them 40-60 characters, clear over clever, and test benefit vs. curiosity vs. direct patterns rather than guessing.
