I have tried
1: MailChimp (It is good but ummm, well lets just say not in accordance with my needs)
2: Mailwizz: (I like it and kinda like the features too)
3: Campaigns+: (Multiple features, more than i expected, but i have no idea about reliability)
4: Aweber: (once again good but I have no idea about how reliable it can be in the longer run)
I have tried others too but these 4 stood out. They also sort of cover my cost too since I am not looking to invest more than $5k at the moment.
I shall be very thankful if someone can guide me on which software should I pick. Thankyou
