Trusted by lead gen teams and agencies
Grow your MailUp list with better sign-up forms
This integration allows you to automate your email marketing by triggering actions whenever a new form submission is received. You can choose to add the recipient to a mailing list, create a new email message, and much more.
In practice, that means new subscribers reach MailUp with the right tags, lists or segments already applied, so your welcome sequence starts straight away. Because Growform forms are multi-step, you can ask a qualifying question or two before the email address without hurting sign-up rates, and pass those answers into MailUp to personalize what people receive.
Collect up to 2x more leads and send them straight to MailUp
Growform makes it easy to build multi-step forms that get more leads.
We’ve taken years of experience in conversion rate optimization and landing page best practice and distilled it into an easy-to-use form builder.
Every submission is sent to MailUp automatically, safely and securely.
A MailUp form that looks like your brand
Don’t settle for “yet another MailUp form” – use advanced customization options like custom fonts, background images and color schemes to build a form that looks just like your brand.
A good form is more than just its appearance – it’s about the user experience. Growform ensures your forms are responsive, giving your customers an exceptional experience whether they’re on a desktop or on the go with their mobile device.
If you’re not sure where to start, there’s a template for pretty much every industry!
