Why Email Integration Transforms Your Funnel Strategy
ClickFunnels email integration connects your sales funnels with email marketing services to automatically capture leads, send follow-ups, and deliver transactional messages. By integrating, you can:
- Use SMTP Integration: Connect services like Mailgun or SendGrid for superior deliverability.
- Make Direct API Connections: Integrate with autoresponders for seamless lead management.
- Use HTML Forms: Connect almost any email service with custom HTML forms.
- Create Custom Email Addresses: Use branded emails for professional communication.
- Build Automated Workflows: Trigger email sequences based on customer actions.
Integrating email services with your funnels transforms static landing pages into dynamic lead generation machines that automatically nurture prospects. The key difference between ClickFunnels' default email system and a custom SMTP integration is control. While the default system is functional, connecting your own email service provider gives you advanced deliverability, detailed analytics, and control over your sender reputation.
Without proper email integration, you're collecting leads that may never hear from you again. Automated follow-up sequences ensure every lead gets the right message at the right time, preventing potential customers from disappearing.

The Core of ClickFunnels Email Integration: Understanding SMTP
ClickFunnels email integration relies on SMTP (Simple Mail Transfer Protocol), the internet's postal service. When someone interacts with your funnel, SMTP ensures your automated emails reach their inbox. Integrating SMTP gives your funnels the power to communicate directly with customers.
There are two main types of emails to understand: transactional emails (welcome messages, order confirmations, password resets) are triggered by specific user actions and have high open rates. Marketing emails (newsletters, promotions, nurture sequences) are designed to build relationships and guide prospects through your funnel.
ClickFunnels offers two SMTP integration types to handle these emails:
| SMTP Type | What It Does | Perfect For |
|---|---|---|
| Transactional Only | Handles action-triggered emails that customers expect after interacting with your funnels | Welcome emails, order confirmations, password resets, digital product fulfillment, shipping notifications |
| Transactional & Marketing | Everything transactional emails do, plus full marketing campaign capabilities through third-party providers | All transactional needs plus newsletters, promotional broadcasts, automated email sequences, A/B testing campaigns |
The transactional-only option is great for simpler businesses, but the transactional and marketing integration is essential for scaling with sophisticated campaigns. ClickFunnels supports powerful SMTP services like Sendgrid, Mailgun, Mandrill, and SparkPost, all designed for high-volume sending and excellent deliverability.
For a full overview, see ClickFunnels' guide on Sending Emails from your ClickFunnels Account – SMTP Email Integrations.
Setting Up a Transactional SMTP
The ClickFunnels Transactional Email service is ideal for Basic plan users or those needing reliable delivery for essential business emails like receipts and welcome messages. Setup requires a secured custom domain and a professional business email address on that domain.
In your workspace settings, add a new transactional integration and configure your details. ClickFunnels will provide DNS records to add to your domain host. Be aware that DNS changes can take up to 48 hours to propagate, so verification may not be instant. For detailed instructions, see this guide: Learn how to set up your ClickFunnels Transactional Email.
Setting Up a Transactional & Marketing SMTP
To enable full-scale marketing, a transactional and marketing SMTP integration connects ClickFunnels with a specialized email service provider. You'll need a secured custom domain, an account with a supported SMTP service (like Sendgrid or Mailgun), and a professional business email address. Avoid using free email providers like Gmail, as they can harm deliverability.
The process involves entering your SMTP credentials (server, port, username, password) into your ClickFunnels settings. This integration also supports webhooks, allowing your SMTP provider to send real-time data on opens, clicks, and bounces back to ClickFunnels.
A Step-by-Step Guide to Mailgun SMTP Integration
Mailgun is a robust choice for ClickFunnels email integration. Start by setting up your domain in Mailgun, preferably using a subdomain like mg.yourdomain.com to protect your main domain's reputation.
Mailgun will generate several DNS records (TXT, MX, CNAME) that you must add to your domain host exactly as provided. DNS verification can take up to 48 hours, so be patient if it doesn't pass immediately.
Once verified, go to your ClickFunnels email integration settings to create a new transactional and marketing connection. Use smtp.mailgun.org as the server, port 587, and the SMTP credentials from your Mailgun dashboard. Your username will be similar to postmaster@mg.yourdomain.com, and you'll use the specific SMTP password provided by Mailgun, not your account login password.
For a complete walkthrough, refer to the official guide: Setting Up Mailgun SMTP.
Domain and DNS: The Technical Keys to Email Success
For ClickFunnels email integration, correct DNS configuration is critical for deliverability. Your domain's DNS records act as an address book, telling email servers that your messages are legitimate. Without proper setup, your emails can land in spam or disappear.
When setting up an SMTP integration, you'll work with three main DNS record types:
- TXT Records: Handle email authentication via SPF and DKIM, proving your SMTP server is authorized to send emails for your domain.
- MX Records: Route incoming mail, which some SMTP providers require for proper subdomain function.
- CNAME Records: Act as redirects, often for tracking purposes, linking a subdomain to your SMTP provider's infrastructure.
Your SMTP provider will give you the exact records to add to your DNS management area (e.g., your domain registrar or Cloudflare). Add these records precisely as provided. DNS propagation can take up to 48 hours, so your integration may show as “pending” during this time, which is normal.
Using a secured custom domain is essential for building trust and deliverability. An email from support@yourbrand.com is far more credible than a generic address. Whether you use a ClickFunnels domain or an External domain, proper DNS configuration is the key to reaching the inbox.
Managing Custom Email Addresses
After setting up SMTP, manage your custom “From” addresses for brand consistency. Add a new address in Workspace Settings > Email Settings > Email Addresses. You'll provide a nickname, a sender name, the email address itself (support@yourdomain.com), and select your connected domain.
You can update or archive addresses as needed. Addresses are archived, not permanently deleted, to prevent breaking active workflows. If an archived address is in use, ClickFunnels will prompt you to select a replacement.
In Email Settings, you can also assign specific addresses for System Emails (like order confirmations) and marketing campaigns to maintain consistent branding. Avoid using the shared @clickfunnelsmail.com addresses for business; they are for testing only and are limited to 100 sends.
Crucially, ClickFunnels sends emails but does not provide an inbox for replies. You must set up an inbox with an external service like Google Workspace or Zoho Mail for each custom address to receive customer responses.
For a detailed guide, see How to Add a Custom Email Address in ClickFunnels.
Beyond SMTP: Other ClickFunnels Email Integration Methods
Beyond sending emails via SMTP, other integrations focus on list building and lead management. These methods connect your funnels to email marketing platforms, automatically adding new leads to your campaigns without manual data entry.
Direct API integrations are a top choice, creating a robust, real-time connection between ClickFunnels and Third Party Autoresponders like many popular email marketing services. When a user fills out a form, they are instantly added to your email list. These connections are simple to set up, reliable, and allow for rich data exchange, including custom fields and tags for segmentation. This real-time sync means new leads immediately enter the correct email sequence, keeping your marketing automated 24/7.
To learn more about these powerful connections, see our guide on ClickFunnels Autoresponder Integration.
How to Integrate an Autoresponder
Integrating a third-party autoresponder is a reliable way to automate follow-up sequences. A ClickFunnels email integration automatically sends leads from your funnels into your autoresponder account, where you can nurture them with Automated Follow-up Emails.
Setup is straightforward: connect the autoresponder in your ClickFunnels account settings, typically by entering your login credentials or an API key. Then, on your individual funnel pages, access the integration settings to choose the destination list. Here, you can add specific tags to segment your audience based on their actions. For example, tag someone who downloaded a social media guide as “SocialMedia_Lead” to trigger a relevant email sequence. This level of personalization dramatically improves conversion rates.
Using the HTML Form for a Universal Clickfunnels Email Integration
If your email platform lacks a direct API integration, the HTML form method is a universal solution. It works by embedding the raw HTML code from your email provider's opt-in form into your ClickFunnels page. When a user submits the form, their data is passed through the HTML code to your email service.
This method is ideal for smaller email providers or when you need to pass custom fields not supported by an API. To set it up, find the raw, HTML-only (no JavaScript) opt-in form code from your email provider. In your ClickFunnels page integration settings, select the “HTML form” option, paste the code, and then map your ClickFunnels form fields to the corresponding fields from your email provider's form.
Important Limitation: HTML form integrations do not work on ClickFunnels order pages. Using them on a checkout page can prevent orders from processing. Reserve this method for lead capture pages and other non-transactional forms. Always test your integration in a private browser window.
For a complete guide, see the official documentation: HTML Email Form Integration.
Management, Troubleshooting, and Best Practices
Properly managing your ClickFunnels email integration involves understanding plan limits, maintaining a good sender reputation, and knowing how to troubleshoot common problems.
Plan Limitations and Email Capabilities
Your ClickFunnels plan determines your email capabilities:
- ClickFunnels Basic plan: Allows one SMTP service connection. This is ideal for sending emails via the
Automationstab in your funnels for essential follow-ups. - ClickFunnels Platinum plan: Allows up to three SMTP services. This enables sending through
Automations,Broadcasts, andFollow-Up Funnels, which is useful for managing multiple brands or separating transactional and marketing emails.
For more details on plan features, refer to the documentation on Automations.
Spam Policies and Sender Reputation
Email deliverability is critical. ClickFunnels restricts accounts with high spam reports, bounces, or drops to protect the platform. You are responsible for maintaining a clean sender reputation, which is built on low bounce rates, minimal spam complaints, and high engagement. Always use a secured custom domain and a professional email address.
If your sending is restricted, you can often restore your reputation by sending only to your most engaged subscribers (e.g., those who have interacted in the last 30 days) to demonstrate positive engagement.
Troubleshooting Common Issues
If you encounter problems with your ClickFunnels email integration, check these common issues:
If emails aren't sending:
- Incorrect Credentials: Double-check that your SMTP username, password/API key, server, and port are entered correctly.
- DNS Propagation: DNS changes can take up to 48 hours to verify. Be patient after updating records.
- Provider Account Issues: Ensure your SMTP provider account is active, in good standing, and has a valid payment method if required.
- Firewall Blocks: Check if your SMTP provider's firewall is blocking access from ClickFunnels' servers.
If emails land in spam:
- Authentication: Verify that your SPF, DKIM, and DMARC records are correctly set up for your domain.
- Content and Engagement: Avoid spammy content and work to improve open and click rates, as low engagement can hurt deliverability.
Using MessageHub for Inbox Management
While SMTP handles outbound sending, MessageHub in ClickFunnels manages inbound customer conversations. You can integrate an existing email account (like support@yourdomain.com) into a unified inbox. This centralizes communication and allows for team collaboration features like assigning conversations and leaving internal notes. MessageHub handles receiving and managing replies, while your SMTP integration handles sending, creating a complete communication system.
Frequently Asked Questions about ClickFunnels Email Integration
Here are answers to the most common questions about setting up ClickFunnels email integration.
What's the difference between using ClickFunnels' default email sending and a custom SMTP?
ClickFunnels' default sending uses a shared email infrastructure with limited control over deliverability and no advanced tracking. It's suitable for basic internal notifications.
A custom SMTP integration connects a dedicated service like Sendgrid or Mailgun. This gives you full control over your sender reputation, authentication (SPF, DKIM), and deliverability. You also get advanced tracking of opens, clicks, and bounces. For any serious email marketing, a custom SMTP is essential.
How many SMTPs can I connect to my ClickFunnels account?
This depends on your ClickFunnels plan:
- ClickFunnels Basic plan: You can connect one SMTP service.
- ClickFunnels Platinum plan: You can connect up to three SMTP services.
Multiple SMTPs are useful for managing different brands or separating transactional emails from marketing campaigns to protect your sender reputation.
Why are my emails not sending after setting up my Clickfunnels email integration?
If your emails aren't sending, run through this troubleshooting checklist:
- Check DNS Propagation: Have you waited up to 48 hours for your DNS records (SPF, DKIM) to verify? Double-check that they were entered without typos.
- Verify Credentials: Are your SMTP API key/password, server, and port number copied exactly from your provider's dashboard? An SMTP password is often different from your account login password.
- Check Provider Account Status: Log in to your SMTP provider. Is your account active? Is there a valid payment method on file? Have you exceeded your sending limits?
- Rule Out Firewall Blocks: Check if your provider's security settings or firewall could be blocking the connection from ClickFunnels.
Methodically checking these common issues will typically resolve the problem.
