No one is better, both are good and both have different usecases, instantly is way bigger than smartlead for sure in terms of customers + revenue
If you are using it for yourself and looking for easy to use software - instantly
If you have an agency with multiple clients --- I like smartlead better ----
Both are great, but in general:
Instantly = better deliverability + cleaner UI + faster sending at scaleSmartlead = more automation + deeper routing + advanced inbox rotation
If you want simple + high deliverability, go Instantly.
If you want complex workflows + heavy automation, go Smartlead.
