I have bought Tier 2 long time back. There's only zapier automation and Google CSV uploads for campaigns. I asked them for pabbly, they said it will release in September 2024. To my surprise, they released pabbly but on their highest tier only. Without API Integration, this product is useless.
And they have email warmup feature which will bring so much spam to your inbox. Sending emails also have problems, it doesn't send to all the list, only a selected people get email.
