Frequently Asked Questions

What is the best time to send cold emails?

The best time to send cold emails is Tuesday through Thursday, between 8-10 AM and 2-5 PM in your recipient's timezone. Avoid Mondays and Fridays when inboxes are typically fuller.

How many follow-ups should I send?

Send 3-5 follow-up emails spaced 3-7 days apart. Each follow-up should provide new value and have a different angle. Stop if you receive a response or after the 5th attempt.

How can I improve my email open rates?

Focus on compelling subject lines (6-10 words), personalize the sender name, ensure good sender reputation, and send at optimal times. A/B test different approaches to find what works for your audience.

What makes a good email call-to-action?

A good CTA is specific, low-commitment, and valuable to the recipient. Instead of 'Let me know if interested,' try 'Would you be open to a 15-minute call Tuesday to discuss how we helped Company X achieve Y?'
