You may need an autoresponder. I use getresponse, but there are many others. I also use clickfunnels, which also integrates to WP to collect leads and into your email account!

I use popup builder which has been working good for me. But there are probably better.

getresponse is good for this

I used popup domination to increase my optins by 500%

Don't get excited though.

It's one thing to recruit people to your list, it's another to get them to buy anything.

I ended up dropping PD for a simple Aweber basic form using reverse optin tricks.

My conversion rate went through the roof.

No WP plugin needed. Common sense and the ability to learn from your experiences (and read your stats the right way) are crucial though.

Thrive Leads for the form capture and a smart redirect/button scenarios for people who just signed up.

You also need an auto responder. Invest in ActiveCampaign's $8/mo lite plan or Drip.co is free for until 100 subscribers.

Hey pal,all you need is [GWA] Autoresponder.
I can help you configure it if you will need.

You need an autoreposnder or email marketing platform for this. I use ActiveTrail and they have a landing page builder as well which is very helpful for newbies in email marketing.

I've always used GetResponse for all of my websites. It's not too hard to learn how to use it too.

You need an autoresponder (whether you use a WP plugin or not), and I've used GetResponse for years - very straightforward to use. And GetResponse can do a popup if you want. About Thrive Leads - I've been using it for a few months and it's way too complex for what you need. Interface is confusing. Their technical support is poor.

If you are with get response you can use the get response plugin I am sure a webber and the others have the same Robert

Popup builder is good...
