Which is the best in your opinion?
ActiveCampaign of course has more about automation: it has designed primarly for that. It has integration for all, and the support is very fast.
SendLane has automation too, less choices than ActiveCampaign, but it has also opt-in page builder.
They are not customizable, and if you need something more professional, you have to go to LeadPages or OptimizePress.
However, SendLane can send the mail at the time the user has been tracked to open it more frequently, which is a very good option.
So, in your opinion, what are the pros and cons and what is the best one?
