When You Need This
You'll use sender email settings when you:
Set up your SendX account for the first time
Want emails to come from different team members or departments
Need to route replies to a specific support or sales inbox
Rebrand your company or change your email domain
Add new team members who will send campaigns
Configuring your sender settings correctly helps maintain your sender reputation and ensures replies reach the right team member.
Understanding Sender vs. Reply-To Email
Before configuring your settings, it's important to understand the difference:
From Email (Sender Email): The email address that appears in the "From" field when recipients receive your email. This is who the email appears to come from.
Reply-To Email: The email address where replies will be sent when recipients click the reply button.
These can be different addresses. For example, you might send from john@company.com but route replies to support@company.com. If you don't specify a reply-to address, replies automatically go to your From Email address.
Important Requirements Before You Begin
From Email addresses must be verified: You cannot send emails from unverified email addresses. SendX requires domain authentication (SPF/DKIM setup) before you can use an address as a sender.
Business domains only: You must use your own business domain (like yourname@yourcompany.com). Publicly available email providers like Gmail, Yahoo, or Outlook cannot be authenticated and used as From Email addresses in SendX.
Reply-To addresses don't require verification: You can set any valid email address as your Reply-To address without authentication.
How to Add and Configure Sender Email Settings
Follow these steps to set up your sender information:
Click your Profile icon at the top right corner of your SendX dashboard
Select Settings from the dropdown menu
Navigate to the Sender page
Click Add New Sender (if adding your first sender) or the + icon (if adding additional senders)
Enter your sender details:
From Name: How your name will appear to recipients (e.g., "Sarah from Acme Inc")
From Email: Your verified business email address
Reply-To Email (optional): Where you want replies sent (if different from From Email)
Click Save to add the sender
Note: If your domain is not yet verified or whitelisted, you'll see a notification and won't be able to use that sender until verification is complete. Contact your account administrator to complete domain authentication.
How to Change Your Default Sender
Your default sender is automatically selected when creating new campaigns. To change which sender is your default:
Go to Profile > Settings > Sender
Locate the sender you want to set as default from your list of configured senders
Click the Set as Default button next to that sender
Your new default sender is now active for all future campaigns
Changing your default sender only affects new campaigns you create going forward. It does not change the sender information for campaigns you've already sent.
How to Use Different Senders for Individual Campaigns
While sender settings are account level, you have flexibility when creating campaigns:
Option 1: Choose from existing senders When creating a campaign, you can select any of your configured senders from the dropdown menu in the sender settings section.
Option 2: Create a new sender on the fly While creating a campaign, you can add a new sender directly from the campaign creation workflow. This new sender will be saved to your account and available for future campaigns.
How Sender Settings Work with Workflows
Automation workflows (your visual automation builders) use the same sender settings as your campaigns. Any sender you configure in Settings > Sender will be available when setting up workflow emails.
Managing Multiple Senders
You can create and save as many verified sender email addresses as you need. This is useful for:
Different team members sending campaigns (sales@, support@, newsletter@)
Different brands or product lines under one account
Testing different sender identities for engagement
Best practice: Regularly review your sender list under Settings > Sender and remove any old or irrelevant senders. If a team member accidentally uses an outdated sender or a domain you no longer own, it can cause serious deliverability issues and damage your sender reputation.
Important Notes and Limitations
Account-wide settings: Sender configurations apply to your entire SendX account, not individual users. All team members can see and use any configured sender.
Permission levels: All team members can change sender settings and create new senders. If you need to restrict access, review your team permissions.
Domain verification is required: You cannot bypass the domain verification requirement. If you're seeing errors when adding a sender, verify that your domain's SPF and DKIM records are properly configured.
Reply routing: Always test your reply-to configuration by sending a test campaign and replying to it. Verify that replies arrive at the intended inbox.
Common Questions and Troubleshooting
Q: Can I use my Gmail or Yahoo address as my From Email?
No. Publicly available email providers cannot be authenticated in SendX. You must use your own business domain email address. You can, however, set a Gmail or Yahoo address as your Reply-To address if needed.
Q: Why can't I use a sender I just created?
Your domain must be verified and whitelisted before you can send from that address. Check with your account administrator to confirm your domain authentication is complete. You'll see a clear notification if the domain is not yet verified.
Q: If I change my default sender, will it affect campaigns I've already sent?
No. Changing your default sender only affects new campaigns created after the change. Previously sent campaigns remain unchanged.
Q: Where do replies go if I don't set a Reply-To address?
Replies automatically go to your From Email address. You only need to configure a separate Reply-To address if you want replies directed somewhere different.
Q: I accidentally sent a campaign from the wrong sender. What should I do?
Unfortunately, you cannot change the sender after a campaign is sent. For future prevention, double check your sender selection before sending, and consider removing old or unused senders from your account to avoid accidental selection.
Q: Can I set different Reply-To addresses for different campaigns?
Yes. While you configure Reply-To addresses at the sender level (Settings > Sender), you can create multiple senders with different Reply-To addresses and choose which one to use for each campaign.
Q: My team member added a sender but it's showing as unverified. What's wrong?
The domain for that email address hasn't been authenticated yet. Your account administrator needs to complete the domain verification process (SPF/DKIM setup) before anyone can send from that domain.
Q: Should I create separate senders for transactional vs. marketing emails?
Yes, this is recommended. Using different sender identities for different email types helps maintain better deliverability and gives recipients clear expectations about the content they're receiving.
