The Connections tab is where you connect your email tool. You do it once, and every funnel you build can send leads to it. Every lead is saved on your own site first, on the Leads screen, and then sent on, so a bad day at your email tool never costs you a lead.
Where to find it:

Open AiX Funnels, then Connections. The intro card reads Connect Your Email Tool. Below it is one card per tool, each with a Connected or Not Connected badge, and a final card called Works With Anything Else.
The built in connections:
- ActiveCampaign: add optins to a list and tag them
- AWeber (Developer OAuth): full read and write access to your AWeber lists
- AWeber (Legacy): the quick way in, with no AWeber app to create
- Brevo: add optins to any Brevo list. A repeat optin updates the contact
- EmailOctopus: add optins to any list, with tags. Marked Beta
- FluentCRM: runs inside WordPress, nothing to paste
- GetResponse: add optins to any list, with tags
- Kit (ConvertKit): subscribe optins to any Kit form, with tags
- Klaviyo: add optins to any Klaviyo list. Marked Beta
- Mailchimp: add optins to any audience, with tags
- MailerLite: add optins to any MailerLite group
- ResultsAiX Mailer: runs inside WordPress, nothing to paste
- Sendy: add optins to a list in your own Sendy installation
- The Systeme card: adds optins as contacts and applies a tag, which is how Systeme triggers automations. Marked Beta
How to connect one:

- Open Connections and find your tool.
- Read the steps under the key box. Each card says exactly where the key lives in that service, for example: in Mailchimp click your profile, then Account And Billing, Extras, API Keys.
- Use the Open link under the box to go straight to the right page in that service.
- Paste the key and press Save.
- Press Test Connection. A good test names your tool and confirms the connection.
- The badge changes to Connected and the card gets a gold outline.
If a test fails, you see the provider's own message rather than a vague error, so you can act on it. A rejected key, a missing permission and a provider outage all read differently. Your key is masked as soon as it is saved, and a Disconnect button appears for when you want to remove it.
The ones that work a little differently:


- AWeber (Developer OAuth) connects through AWeber itself. Create a small app in AWeber following the steps on the card, set Client Type to Public, and paste the OAuth Redirect URL for your app shown on the card. Your app name must not contain the word AWeber. Save your Client ID, press Authorize, then paste the code AWeber shows you into Authorization code and press Save again. No password and no client secret is stored on your site.
- AWeber (Legacy) needs only your AWeber list name, and an optional Web form ID. It sends only, so it cannot read your lists back, and subscribers are sent from your visitor's own browser. The lead is saved on your site first either way.
- Sendy runs on your own server, so Sendy URL is one of the fields, the root address only, with no trailing slash. Sendy cannot list your lists, so you paste the List ID on the form by hand.
- The Systeme card has no lists. Tags are how Systeme segments contacts and starts automations, so a tag is what you choose.
- FluentCRM runs on this site. If the free FluentCRM plugin is active, it is connected. Run Test Connection to confirm.
- ResultsAiX Mailer runs on this site too. If Mailer is active it is connected, and your Mailer lists load straight into the form. Leads behave exactly like someone who used a Mailer form: the list's double opt in setting is respected, addresses on your suppression list are refused, tags are added without wiping existing ones, and any Mailer automation that starts on joining a list or on a tag runs straight away.
- ActiveCampaign needs two fields, API URL and API Key, from the same Settings, Developer screen.
- Brevo needs a v3 key. EmailOctopus needs a current v2 key. Klaviyo needs a Private API Key that starts with pk_.
Not on the list?

The Works With Anything Else card says it: every optin form can also post to a webhook, which covers Zapier, Make, n8n, your own CRM, or any tool that accepts a POST. You set it on the form itself, under Where These Leads Go. When WP Sync is active, your saved WP Sync bridges appear as a destination too.
A real example:
Calm Kitchen uses two tools. The free guide feeds Mailchimp, so Sarah saved her Mailchimp key and tested it. The challenge was set up years ago in Kit, so she connected Kit (ConvertKit) as well. Both cards show Connected, and both appear in the Send To list on every form.
Where your keys live:
Encrypted on your own server. They are masked as soon as they are saved and never shown in full again, and nothing is sent to us.
What to do next:
Connecting a tool tells the plugin what you use. Telling each form where to send its leads is the next step. See Where Your Leads Go, And What Happens After The Optin.
