## Frequently asked questions

### How long should an email subject line be?

Aim for under 50 characters so it displays fully on mobile, where most email is opened. Short, specific subject lines consistently beat long, vague ones.

### What hurts email deliverability?

All-caps, excessive punctuation, spammy words, and misleading promises can trip spam filters and erode trust. These subject lines are written to be punchy but clean.

### What's a good email open rate?

It varies by industry, but 20 to 40 percent is a common healthy range. The subject line is the biggest lever, so testing a few strong options is the fastest way to lift it.

### Should I use emojis in subject lines?

Sparingly. A single relevant emoji can help a subject line stand out, but overuse looks spammy and can hurt deliverability. Test before committing.

### How do I A/B test subject lines?

Send two variants to small, equal segments of your list, then send the winner to the rest. Most email platforms automate this. Generate several options here to have strong candidates.
