I was just wondering,
I have few blogs with good traffic.
I had some basic tools but want to go to the next step to have strong conversion rates.
I tried ThriveLeads that appears to be super buggy with a support not very reliable...
Looking for the best tools that are working well and possibly be affordable.
Let me know!
Thanks 
Maybe try OptinMonster? - http://optinmonster.com/features/
Lead pages is also good if you want lander templates as well - https://www.leadpages.net/features
I see aweber being used by a lot of bloggers, not sure if it's the "best" option or not tho. I would like to know what people are using too as I will soon need a tool like this myself. Any suggestions?
I'm using GetResponse for catching e-mails and mailing my blog subscribers, but basically each mailing provider offers a plugin for WordPress as well.
I've been using Optin Monster on my sites and it's pretty good.
Definitely cheaper than most of the exit-intent technologies used by big brands. You can also use VIP20OFF to get additional 20% of any package.
Using this one: https://codecanyon.net/item/ninja-po...dpress/3476479 .
I've been using OptinCat, but largely because I didn't want to spend half a day writing my own.
My guess is that most of the plugins will do roughly the same thing - pop a popup when the mouse goes off the window or after a certain period of time. I'd be interested to hear if Optin Monster or other plugins are actually doing something clever beyond that.
Protip: if you're also doing in-page subscribe forms, which you probably should, use a single-button approach which then pops a form, not an inline form. Definitely increases conversions for most people.
As for which mailing list provider to use - Aweber does the job, certainly, but these days I'd look at a programmatic mailer with more sophisticated automated features. Something like Drip is good, but there are a bunch of them popping up these days and I don't think there's a clear winner yet. (I'd also be interested in more recommendations there!)
Finally I'm trying Bloom now,
Seems decent for the price, even if the AB testing tool could be improved
I use mailchimp for my blog. It's powerful and simple.
