What Is an Email Sequence?
An email sequence is a series of pre-written, auto-sent emails triggered by a user action (signup, purchase, inactivity). Unlike a one-off blast, sequences carry narrative and build trust.

Q: How many emails in welcome?
A: 3–7. Fewer than 3 loses opportunity; more than 7 fatigues.
Q: Plain text or HTML?
A: Plain text feels personal. HTML signals "marketing." Test both.
Q: Send times?
A: Tues/Thurs 8–10 AM local work well. Test with your list.
Q: Personalization?
A: First name only. Over-personalization (e.g., "I see you're from ") feels creepy.
Q: Emojis in subject?
A: 1 max. None for enterprise.
Q: GDPR double opt-in?
A: Required in EU. Recommended everywhere.
