Custom Mail Sender allows organizations to send webinar communications using branded sender names and email addresses instead of the webinar.net default sender information.
This feature supports sender configuration at the client, account, and webinar folder levels, allowing different teams, departments, brands, or event programs to use different email identities.
Availability of this feature may depend on your subscription or contract.
Overview
By default, webinar emails are sent using the platform's default sender information:
Sender Name: webinar.net
Sender Email Address: noreply@webinar.net
With Custom Mail Sender configured, webinar communications can be sent using your organization's preferred sender identity.
Example:
Example, Inc. webinars@example.com
Using a branded sender identity helps improve attendee recognition, trust, and email deliverability.
Important Notes
Custom Mail Sender is an optional add-on.
Availability may depend on your subscription plan or contract.
The sender email address must be a valid mailbox capable of receiving email.
DNS authentication may be required to comply with modern email delivery standards.
Multiple Mail Sender configurations can be assigned and used across different webinar folders.
Requirements
Before requesting setup, prepare the following information:
The sender name you want displayed
Example: Example, Inc.
The sender email address you want used
Example: webinars@example.com
Access to a domain administrator who can update DNS records
How Setup Works
Once setup has been completed successfully:
webinar.net will send emails on behalf of your domain
Recipient inboxes will display your custom sender information
DKIM authentication will be configured to improve email deliverability
Setup Instructions
Step 1: Submit Your Request
Contact the webinar.net Support Team and provide:
Your desired sender name
Your desired sender email address
Step 2: Receive DKIM DNS Records
The webinar.net team will initialize the setup and provide the DNS records required for DKIM authentication.
Step 3: Add DNS Records
Your domain administrator must add the provided DNS records to your domain configuration.
Step 4: AWS Verification
After the DNS records propagate, AWS will automatically verify the DKIM configuration.
Step 5: Confirm Email Ownership
AWS will send a verification email from:
This verification email will be delivered to the custom sender email address you provided:
Open the email and click the verification link to confirm ownership of the address.
Step 6: Final Configuration
After verification is completed:
webinar.net will finalize the configuration
A test email may be sent for validation
The Mail Sender configuration will become available for use within your account
Assigning Mail Sender Information
Once one or more Mail Sender configurations have been created for your account, they can be assigned at the account level or to specific webinar folders.
This allows different webinar programs, departments, brands, or clients to send emails using different sender identities.
Assign a Mail Sender to a Webinar Folder
Open the desired webinar folder.
Select the folder's Settings option:
Locate the Mail Sender Information setting:
Select one of the available Mail Sender configurations from the drop-down.
Save the folder settings.
All webinars created within that folder will use the selected Mail Sender configuration when sending attendee emails.
Working with Subfolders
Mail Sender assignments can also be configured on nested folders and subfolders.
Example:
Root Folder → Mail Sender A
Parent Folder → Mail Sender B
Child Folder → Mail Sender C
This structure allows organizations to create separate email branding for different teams, departments, customers, or webinar programs while maintaining centralized management.
Mail Sender Selection Priority
When a webinar belongs to a folder hierarchy, webinar.net determines which Mail Sender configuration to use based on the following priority order:
Child Webinar Folder
Parent Webinar Folder
Account-Level Configuration
Client-Level Configuration
Platform Default
Example
For a webinar located inside a child folder:
If the child folder has a Mail Sender configured, that configuration is used.
Otherwise, the system checks the parent folder.
Otherwise, the system checks the account-level configuration.
Otherwise, the system checks the client-level configuration.
If no custom configuration exists, the webinar.net default sender information is used.
This hierarchy allows highly specific branding while still providing fallback behavior when a folder-specific sender has not been configured.
Reply-To Addresses
Mail Sender configurations can also include a Reply-To email address.
When configured:
The Reply-To address is displayed in the folder settings.
Attendee replies are directed to the Reply-To mailbox instead of the sender address.
This allows organizations to route attendee responses to shared inboxes, support teams, or event coordinators.
About DKIM Authentication
DKIM (DomainKeys Identified Mail) is an email authentication standard that helps improve email deliverability and verifies that messages are authorized by your domain.
Major email providers, including Gmail and Yahoo, require authenticated email sending for many automated communications.
Without proper authentication:
Emails may be filtered as spam
Delivery rates may be reduced
Some messages may be rejected entirely
Because of this, DNS verification and DKIM configuration must be completed before Custom Mail Sender functionality can be enabled.
