Which Email Marketing Tools Integrate Natively With WordPress Forms?

Your signup form and your email list should work as one system, not two tabs you copy names between. That’s the whole job of email marketing integrations for WordPress forms: every submission adds the contact to your list automatically, already tagged and ready for your next campaign.

WPForms connects natively with 13 email marketing platforms, from Mailchimp to Kit to Klaviyo.

In this post, I’ll go through all 13, what each one does best, and how to figure out which one belongs in your stack.

Which Email Marketing Tools Integrate Natively With WordPress Forms?

WPForms has native addons for 13 email marketing platforms, and every one of them is set up the same way: inside the form builder, no code involved. Here’s the full list, plus how to pick the right one for your site.

What Counts as a Native Integration?

A native integration is a direct connection between your form and your email platform, built and maintained by the WPForms team. You set it up inside the form builder, map your form fields to your list fields once, and the connection runs on every submission from then on.

That’s different from routing submissions through a middleman like Zapier. Zapier is great when there’s no other option (more on that below), but a native addon is faster to set up, doesn’t add a monthly bill for a separate automation tool, and doesn’t put a third service between your lead and your list.

1. Mailchimp

Best for: small businesses building their first real email list.

Mailchimp is the most popular email platform among small businesses, and the pairing with WPForms reflects that. Connect the Mailchimp addon and every signup, opt-in, or order form can add a contact to the right audience with the right tags and merge fields applied. You map your fields once, and every submission after that grows your list on its own.

If you’ve ever exported contacts from your form plugin and imported them into Mailchimp by hand, this is the addon that ends that chore. The lead gets added the moment they submit, so your welcome email reaches them while they’re still warm.

2. Constant Contact

Best for: getting started without upgrading your plan.

Constant Contact holds a special spot on this list: it’s the one email marketing integration available on every WPForms plan, including Lite. If you want your signup form feeding a real email list from day one, this is the shortest path there.

The platform itself is one of the most beginner-friendly email tools around, which makes it a favorite with small businesses, churches, and nonprofits. Signups flow directly into your Constant Contact list, ready for newsletters, event promotions, and nurture campaigns.

3. Kit (formerly ConvertKit)

Best for: bloggers, podcasters, and creators who run their business on a list.

Kit is the email tool of choice for creators, and the WPForms addon connects to the parts that matter most: tagging and sequences. Wire a form to Kit and every signup gets the right tag and kicks off the right sequence automatically, whether it came from your homepage opt-in, a lead magnet, or a course waitlist.

Tagging is the real story here. When every form applies its own tag, your launches go out to the people who asked for them instead of one broadcast to a flat list.

4. MailerLite

Best for: creators and small teams who want email without the bloat.

MailerLite has a loyal following for one main reason: it stays simple. The WPForms addon matches that spirit. Map your fields, drop in your form, and every signup lands on your list, ready for MailerLite’s automations to take over.

If you’ve been putting off email marketing because every platform demo feels like learning a second job, MailerLite plus WPForms is the low-overhead way in.

5. Brevo (formerly Sendinblue)

Best for: small businesses that want email, SMS, and a CRM in one place.

Brevo bundles email, SMS, and CRM tools into a single platform, and the WPForms addon feeds all of it. One form submission can add a contact who’s reachable by both email and text, without stitching together a separate vendor for each channel.

That makes it a strong pick if your marketing stack has been creeping. One tool and one bill instead of three.

6. MailPoet

Best for: site owners who want email marketing inside WordPress.

MailPoet is the odd one out on this list, in a good way: it runs entirely inside your WordPress dashboard. Your list, your campaigns, and (with the WPForms addon) your signup forms all live in the same place you already work. There’s no separate platform to log into.

It’s an especially good fit for volunteer-run teams. Training someone on one tool is a lot easier than training them on three.

7. AWeber

Best for: automation-first list building with dependable deliverability.

AWeber has been in the email game for decades, and its longtime users stick around for the deliverability and the automations. The WPForms addon drops signups directly into a list, a tag, or an automation campaign, so your welcome sequence starts the moment someone submits.

If your welcome emails still go out by hand, this is the connection that puts them on autopilot.

8. GetResponse

Best for: marketers running email and webinars from one platform.

GetResponse combines email marketing, autoresponders, and webinar tools, which makes it popular with course creators and B2B teams. Connect it to WPForms and your registration and opt-in forms feed the same audience your webinars run on.

That’s the practical win: lead capture, email nurture, and webinar promotion all share one contact database, so nobody falls between systems.

9. Campaign Monitor

Best for: brands and agencies that care about beautiful email.

Campaign Monitor built its reputation on design-forward email, and it tends to attract teams with strong brand standards. The WPForms addon handles the unglamorous half of that equation: getting new contacts into the right list with the right segmentation, automatically.

Gorgeous templates only pay off if the list behind them keeps growing. This connection makes sure it does.

10. Drip

Best for: online stores running behavior-driven email.

Drip is marketing automation built for ecommerce, with abandoned cart flows, post-purchase follow-ups, and segmentation by spend. The WPForms addon passes your form data into that engine, so signups arrive with the tags and triggers Drip’s automations need to do their job.

If you sell online and your email strategy is still “send a broadcast and hope,” Drip plus WPForms is a meaningful upgrade.

11. Klaviyo

Best for: ecommerce brands running segmented email and SMS flows.

Klaviyo has become the email platform of choice for serious online stores, largely because of how deeply it segments customers by behavior and purchase history. The WPForms addon adds new contacts to your Klaviyo lists with their form answers attached, so your flows have real data to work with from the first touch.

If your store’s email revenue lives and dies by segmentation, this is the connection that keeps your signup forms feeding it.

12. SendGrid

Best for: teams that want marketing and transactional email under one roof.

SendGrid (part of Twilio) is best known for deliverability at scale, and it handles both marketing campaigns and the transactional email your site already sends. The WPForms addon adds form contacts to your SendGrid marketing lists, so the platform trusted with your receipts and password resets can grow your audience too.

It’s a natural pick if SendGrid already powers your site’s email and you’d rather deepen one tool than add another.

13. ActiveCampaign

Best for: teams that need automation depth, deal stages, and a sales pipeline.

ActiveCampaign is the deep end of this list: marketing automation plus a CRM and sales pipeline. The WPForms addon can tag a contact, trigger an automation, and move a deal forward from a single form submission.

It’s available on the WPForms Elite plan, and it earns that placement. If your leads should be moving through pipeline stages instead of sitting in an inbox, this is the integration to build on.

What If Your Email Tool Isn’t on This List?

You’re still covered. WPForms connects to 9,000+ apps through Zapier, plus Make and n8n, and the Webhooks addon can send submission data to nearly any platform with an API. Native is the better experience when it’s available, but no email tool is out of reach.

How to Choose the Right Email Marketing Integration

A quick way to narrow it down:

• Just getting started: Constant Contact (it works on every plan) or MailerLite.
• Running a creator business: Kit.
• Want everything inside WordPress: MailPoet.
• Selling online: Klaviyo or Drip, or Brevo if you want SMS on a budget.
• Need serious automation and a sales pipeline: ActiveCampaign.
• Already using one of the 13: stick with it. The best integration is the platform your list already lives on.

FAQs About Email Marketing Integrations for WordPress Forms

What’s the difference between a native integration and connecting through Zapier?

A native integration is a direct connection built and maintained by the WPForms team, configured right inside the form builder. Zapier routes your data through a third service, which works fine but adds another tool to manage and another subscription to pay for. Use native when your platform supports it and Zapier when it doesn’t.

Which email marketing integration works on every WPForms plan?

Constant Contact. It’s included on every plan, Lite included. The other integrations unlock on the Plus plan and above, with ActiveCampaign reserved for Elite.

Do I need to know how to code to set up these integrations?

No. You connect your email platform account once, then map your form fields to your list fields inside the builder. There’s no code involved at any step.

Can one form send contacts to more than one email platform?

Yes. You can add multiple marketing connections to the same form, so a single signup could go to Mailchimp and Brevo at once. Most sites only need one, but the option is there during a platform migration.

Can I add subscribers only when they check an opt-in box?

Yes, and you should. Add a checkbox to your form, then use conditional logic on the marketing connection so contacts are only subscribed when the box is checked. That keeps your list consent-based and your signup flow GDPR-friendly.

Can I tag or segment subscribers based on their form answers?

Yes. Field mapping lets you pass answers into your platform’s custom fields, and platforms like Kit, Mailchimp, and ActiveCampaign support tags on the connection. Conditional logic can also route different answers to different lists or tags.

What happens to a lead if the connection has a problem?

You don’t lose them. Every submission still triggers your email notification and is stored as an entry in your WordPress dashboard, so the contact’s info is safe even if a sync hiccups.

Do I need a separate signup plugin for every email platform?

No, and that’s half the appeal. WPForms handles all 13 platforms through one form builder, so if you ever switch email tools, you swap the connection instead of rebuilding your forms.

Next, Put Your Signup Form to Work

That covers the email marketing integrations for WordPress forms that work natively in WPForms, all 13 of them. Whichever platform runs your list, the setup is the same: build the form, connect the addon, map your fields, and let every submission grow your audience from there.
