How to Setup From Name, From Email Address and Reply Email Address

  • Here you can setup the default from email address (aka sending address also sometimes called sending domain) and reply email address to be used for this ESP connection.
  • With most ESPs and SMTPs you will need to verify the sending email address and reply email address on the ESP vendor's platform, before you can use that ESP connection in Ongage.
  • Simply click on the Add button and type in the desired values.
  • You can setup multiple From Names, From Addresses and Reply Addresses as need, per ESP connection as well as per list (see following section below). You can choose a default value for each, and still choose another set, when sending the email message, from the email message settings step (when setting up an campaign):

(warning) Important Notes:

  1. If you add/change a from email address, you'll often need to verify it in the ESP/SMTP.
  2. If you change the default from email address, only new emails will pick up the new default values. If you copy/reuse an existing email, it will preserve the previous from/reply values.
  3. The "From Name" (e.g., Jon Doe, Jane Smith), can be easily changed as desired in "Step 1: Email Settings" to whatever name you'd like.
  4. In the case of SMTP vendors the 'From Name' can be a dynamic list field. You'll need to set that up in the email message. For more about that see our online 'Content' section, and look there for 'From Name'.

How do I remove the “Sent on behalf of” aka "via" header from the email messages I send from Ongage

If you receive an email message that you sent from Ongage, and instead of the from email address you setup in the ESP setup page, appearing at the top of the email message, you see a "via" or "Sent on behalf" header like this:

My Org via

That means that you did not yet setup the SPF and DKIM records for that sending domain. For more about that, see "About SPF, DKIM and Ongage" under DNS, SPF, DKIM and Related Topics in our online Knowledge Base section.

Also see our online ESP Setup Tutorials for more information about how to verify (aka authenticate) your sending domain on various SMTP vendors.

How to Setup Different Default From Name, From and Reply Addresses for Different Ongage Lists

  • If you have multiple lists, often used for managing different brands/properties/customer lists, you can set a different from name, from email address, and reply email address for each list. 
  • You can set the default from name, from address and reply address for each List by using the List drop-down located right on top of these email attributes. See image above: "List" drop-down.

How to Add an Additional Connection for the Same Vendor

If you have more than one account/sub-account (IPs) with the same ESP/SMTP vendor, for example you have several Mailgun accounts/Subaccounts, you can set up additional connections in Ongage for those, in the following manner:

  1. Go back to the: Vendor Settings → ESP/SMTP Vendors

    1. In the case that you'd like to add an additional SMS connection go to the SMS Vendors sub-menu.
  2. Select the radio button next to the same vendor that you'd like to add an additional connection for:

  3. Click on the 'Save & Next Step >' to proceed to the setup page for that new connection.

  4. When setting up multiple connections with the same vendor, it is particularly recommended to use the 'Account Name' field in the ESP setup page, in order to give a unique label to each connection.

How to Remove an ESP/SMTP/SMS Connection 

  1. Go to: Vendor Settings → My Connections
  2. Under the 'Actions' column choose the 'Deactivate' icon

    The 'Status' column will show the ESP connection is inactive.

  3. Under the same 'Actions' column click on the delete icon:

    The following popup dialog box will then display:

  4. Click on 'Delete' to proceed.


How to use a dynamic field in the 'From Name', 'From Address' and/or 'Reply Address'

(warning) This feature only works with SMTP relays (for a full list of those see our ESP knowledge base).

Since the 'From Address' and 'Reply Address' are set in the 'ESP setup' page (under your My Connections page), that is where you'll need to set this up.

  1. Edit the SMTP connection where you'd like to set this up.
  2. Check the 'Skip Addresses validation' checkbox
  3. Save the connection.
  4. Only after the 'Save' enter a dynamic list field into each 'From Address' and/or 'Reply Address' as needed. For example enter {{sales_rep_from_address}} and {{sales_rep_reply_address}}
  5. Save again after you've entered all From and Reply Addresses.

It is recommended to use the default value feature, in case the list field value is empty, e.g., {{}}

(info) Note: You can also enter here the 'From Name' as well in the same manner.

(info) Note: The From Name can also be used dynamically in the email message. See our Content Help section for how to set a From Name dynamically in the email message.

How to set up Bounce Domain

In those cases where a bounce domain is required, like in the case of mySMTP and Private SMTP, the following is an example of how that definition would be defined in your DNS management system:

(info) Note: In most cases Ongage pulls bounce data from the outbound ESP/SMTP directly via their API or Webhook. Only in relatively rare cases where the ESP/SMTP does not have an API or Webhook for this, and/or does not do the actual bounce processing, a bounce domain needs to be defined and setup for bounce processing.

(warning) Note: The DNS Hosting company "ENOM" does not support custom MX records like those needed in Ongage for bounce domains, like in the the case of mySMTP.
Note: This is needed only for the following vendors mySMTP, Private SMTP, InboxRoad.

In Case your DNS UI Does not Support Pointing a Bounce Sub-domain Domain to our

  1. Create an A record:
  2. Create an MX Record as:      MX 15
  3. Enter the value “” into the bounce domain setup dialog box:

Special Notes for setting up bounce domain in HostGator

In order to set up a bounce domain in HostGator, you'll need to do the following two steps:

Step 1: Create a Subdomain

  • Insert the below:

    In subdomain: bounce."your domain"
    in the document root insert a unique long name
    Document root: /"customer path"/bounce.yourdomain12345

Step 2: Add an MX Entry

  • Click on MX entry

  • The domain should be the same one from step 1
  • Select option "Remote mail Exchange"
