🚀 Hey, Product Hunt community! I'm Alex, the Product Manager at GetESP – a free tool designed to make your email sending smarter. Have you ever wondered why some emails go to spam while others land in the inbox? ESP Matching is a key. 💡 What is ESP Matching? It’s a strategy that improves email deliverability by matching your sending ESP to your recipient’s ESP (e.g., Gmail → Gmail, Outlook → Outlook). This approach helps ensure emails land in the inbox rather than the spam folder. 💯 Why does this matter? ✅ Higher inbox placement – Gmail & Outlook more trust emails sent from their own servers. ✅ Better authentication – Avoid SPF, DKIM & DMARC issues, which can cause emails from different ESPs to be rejected or marked as suspicious. ✅ Faster email delivery – Emails sent within the same ESP have lower latency and faster processing, ensuring they reach recipients without unnecessary delays. ✨ How GetESP Works: ✅ Upload & Analyze – Upload your email list, and our tool will detect the ESP for each email and identify any spam protection tools in use. ✅ Segment by ESP – Get a report showing each email's ESP, then segment it by ESP and spam protection tools. ✅ Send Smarter – Use the segmented list to send emails from the same ESP as your recipient to improve trust and inbox placement. 🎯 Whether you're running cold outreach, marketing campaigns, or transactional emails – ESP Matching can help you reach more people.
