HubSpot Deduplication Simplified - Co-Founder @ Koalify 🐨
0.43% bounce rate on our lastest newsletter send. Our lowest in years.
The only thing we did differently: ran the list through our Koalify 🐨 email validation app first and excluded 60 invalid addresses before hitting send.
Small number, real impact. Every hard bounce chips away at deliverability, clean the list upfront and the rest of your sends land better.
What are you doing to keep the bounce rate of your HubSpot marketing emails low?
