Email Setup & Deliverability
The Inbound Email workflow trigger allows you to automate actions whenever a new email is received on your mailboxes. Whether the sender is an existing contact or someone entirely new, this trigger gives you granular control over how inbound emails enter your workflows – so you can capture leads, route conversations, and respond faster than ever.
What is the Inbound Email Workflow Trigger?
The Inbound Email trigger fires when an inbound email is received on your mailboxes. Unlike the existing Customer Replied trigger (which activates when a contact replies to a message you sent), the Inbound Email trigger is designed to capture all inbound emails – including cold emails from brand-new senders who are not yet in your CRM.
This trigger handles three types of inbound emails:
- Cold Emails – New emails from unknown senders (not in your contacts).
- Warm Emails – New emails from known senders (existing contacts in your CRM).
- Customer Replies – Replies from known senders to an existing email thread (optional, controlled via a setting).
Important: Only email domains configured with Adaptive AI Email or Adaptive AI Email dedicated domains
can track cold inbound emails with this trigger. Two-way sync (Gmail/Outlook), shared domains and other SMTP setups do not support cold inbound email capture and will only capture emails from existing contacts. Details on email behavior are shared further down.
Key Benefits of Using the Inbound Email Trigger
The Inbound Email trigger helps teams turn incoming email activity into automated action. Instead of manually reviewing every mailbox, teams can route, assign, tag, notify, and respond based on the email’s sender, recipient, subject, body, attachments, or workflow source.
- Automate workflows for first-time emails from unknown senders when using a supported dedicated domain.
- Send emails received at,, or into the right workflow path.
- Assign or notify team members as soon as a support-related email arrives.
- Start internal processes when an inbound email includes attachments.
- Choose whether the trigger should run for every reply in an existing thread or only for new email conversations.
- Reference the email subject, body, sender, CC recipients, and message ID in workflow actions.
Prerequisites: Supported Email Configurations
Before configuring this trigger, ensure your sub-account has a supported email setup. The Inbound Email trigger works best for locations configured with:
- Adaptive AI Email dedicated domain
- Adaptive AI Email dedicated domain
If your sub-account does not have a supported dedicated domain configured, it will not capture all types of inbound emails. You will see a banner that will appear in the trigger UI based on your configuration
Key points about dedicated domains and inbound email:
- Any email sent to your dedicated domain will be captured, regardless of the name before the @ symbol. For example, if your domain is acme.com, emails sent to sales@acme.com, support@acme.com, or random@acme.com will all be captured.
- Each sub-account should have a unique dedicated email subdomain. If the same domain is configured across multiple sub-accounts, incoming emails may be routed unpredictably.
- If a non-dedicated domain email setup is configured (e.g., Gmail / Outlook only), the user will be redirected toward email configuration or shown clear guidance that the trigger will not reliably capture cold inbound emails.
Email Behavior Across Different Email Setups
The table below summarizes how inbound email behaves across different email configurations. This will help you understand which setups support the Inbound Email trigger.
Email Setup Type | Cold Inbound Email Captured | Inbound Email from Existing Contact Captured
Adaptive AI Email – Shared Domain | No | Yes, for replies to emails sent from Adaptive AI
Dedicated Domain – Adaptive AI Email or Adaptive AI Email | Yes | Yes
Two-Way Sync – Gmail / Outlook | No | Yes
Other SMTP – SendGrid, Custom SMTP, etc. | No | Yes
How to Set Up the Inbound Email Trigger in Workflows
A clean trigger setup prevents misfires and keeps your automation predictable. Follow these steps to add and configure the Inbound Email trigger.
- 1Log in to your sub-account.
- 2Navigate to Automations > Workflows.
- 3Create a new workflow or open an existing one.
- 4Click on the + Add New Trigger button -> Select Inbound Email from the trigger list.
- 5Enter a clear Trigger Name so it is easy to identify later (e.g., “New Lead from Sales Inbox”).
- 6Click + Add Filters to narrow when the workflow should run (see the Trigger Filters section below for all available options).
- 7Configure the Trigger Settings checkboxes (Track replies in existing threads, Automatically create a contact). See the Trigger Settings section below.
- 8Click Save Trigger.
- 9Add your relevant workflow actions (e.g., Send Email, Create Contact, Add Tag, Assign to User), then Publish the workflow.
Trigger Filters
Filters let you control exactly which inbound emails should activate the workflow. You can combine multiple filters to create precise conditions. Multiple entries can be added using comma separation where supported.
Filter Name | Operators | Example(s) | Notes / Behavior
Email Sent To / Mailbox | Equals, Is any of, Contains, Does not contain | sales@acme.com (equals) @acme.com (contains) | Equals: passes only if the specified email is present in the To / Mailbox field. Is any of: passes if ANY address in the To header matches (supports comma-separated values). Contains / Does Not Contain: substring match on each address.
From | Equals, Contains, Does not contain | john@lead.com @lead.com | Always a single value. Matches the extracted email address, not the display name. Case-insensitive.
CC | Equals, Is any of, Contains, Does not contain | manager@acme.com @acme.com | Equals: passes only if the specified email is present in the CC field. Is any of: passes if ANY address in the To header matches (supports comma-separated values). Contains / Does Not Contain: substring match on each address.
Subject | Equals, Contains, Does not contain | Contains: refund Equals: Request for Quote | Case-insensitive match. Whitespace is trimmed before comparison.
Body (plain text) | Contains, Does not contain | Contains: Order ID: | Matching is run on the plain-text body by default.
Has Attachments | Is true / Is false | TRUE | When set to true, enables attachment-specific downstream actions.
Replied to Workflow | Is, Is not | Select a specific workflow | Filters based on whether the message sent from a specific workflow. Useful for isolating replies to a particular automation. Case-insensitive match. Whitespace is trimmed before
Contact Tag | Has tag, Does not have tag | 16_aug_2022 | Filters contacts by tag. Has tag: fires only if the contact has the selected tag. Does not have tag: fires only if the contact does not have the selected tag. Useful for segmenting automations by audience.
Advanced Settings
The Inbound Email trigger includes an Advanced Settings section (collapsible) that gives you more control over its behavior. Click the Advanced Settings chevron to expand the section.
Trigger Only for New Email Conversations
Type: Toggle | Default: Off
- When OFF (default), the trigger fires for all inbound emails, including replies within existing email threads.
- When ON, the trigger fires only when a new inbound email conversation starts (i.e., a first message, not a reply to an existing thread).
This setting is useful if you want to avoid the trigger firing repeatedly for every back-and-forth reply in an ongoing conversation. Enable this toggle if your workflow should only capture the first inbound email in a thread (e.g., new lead capture, first-touch autoresponder scenarios).
Custom Value Picker Fields
The Inbound Email trigger makes the following custom values available for use in your workflow actions and If/Else conditions. You can use these to personalize follow-up emails, route conversations, parse email content, and more.
Custom Value | Description
{{inboundEmail.messageId}} | Unique message ID of the inbound email
{{inboundEmail.subject}} | Subject line of the inbound email
{{inboundEmail.bodyPlain}} | Plain-text body content of the email
{{inboundEmail.bodyFullPlain}} | Full plain-text body including the entire reply thread
{{inboundEmail.fromEmail}} | Sender’s email address
{{inboundEmail.fromName}} | Sender’s display name
{{inboundEmail.cc}} | CC recipients of the inbound email

Frequently Asked Questions
Q: How is the Inbound Email trigger different from Customer Replied?
The Customer Replied trigger fires when a contact replies to a message you have already sent. The Inbound Email trigger fires on any inbound email – including cold emails from unknown senders. If you need to capture first-contact emails or emails from people not yet in your CRM, use the Inbound Email trigger.
Q: Which email setups support this trigger?
Only Adaptive AI Email and Adaptive AI Email dedicated domains support full inbound email capture. Two-way sync (Gmail/Outlook) and other SMTP providers will only work for emails from existing contacts in the CRM.
Q: Will my existing Customer Replied workflows break?
No. The Customer Replied trigger continues to work exactly as before. The Inbound Email trigger is a separate, new trigger. Your existing configurations are not affected.
Q: Can emails fire both the Inbound Email trigger and the Customer Replied trigger?
It is possible for an email to match both triggers if both are configured in separate workflows. To avoid conflicting scenarios, review your trigger filters and use the “Track replies in existing threads” setting to control overlap.
Q: What happens if the same domain is configured in multiple sub-accounts?
If the same dedicated domain is used across multiple sub-accounts, incoming emails may be routed unpredictably. Each sub-account should have a unique dedicated email subdomain to ensure reliable routing.
Q: Can I prevent the trigger from firing on every reply in a thread?
Yes. Uncheck the “Track replies in existing threads” setting. When disabled, the trigger fires only for new inbound emails / new threads.
Q: Can I filter emails based on multiple criteria?
Yes. You can combine multiple filters (e.g., To / Mailbox + Subject + Has Attachments) to create precise conditions for when the workflow should run.
