Your sender email address is the “From” address your recipients see when they receive your emails. Using a verified custom domain email address improves deliverability and brand trust.
In this article, you'll learn how to add and verify your sender and reply-to email addresses in Omnisend.
Before You Begin
Before adding your own sender email address in Omnisend, you’ll see a shared email address listed under Store settings → Email addresses. This address is automatically assigned by Omnisend and is used while you're still sending from Omnisend’s shared domain.
To ensure proper email delivery and maintain trust with your audience, you should not send from generic or public email domains. Based on industry-wide email authentication standards, these addresses are not supported for bulk sending and may harm your deliverability and engagement rates. Restricted domains include:
@yahoo.com;
@msn.com;
@hotmail.com;
@outlook.com;
@live.com;
@gmail.com, etc.
Your sender email address should be hosted on the same domain you've verified with Omnisend. For example, if your domain is
shop.com, use an address like[email protected]
⚠️ Important: Sending from Omnisend’s shared domain is not recommended. It can lead to poor deliverability, lower engagement, and increase the chance of your emails landing in spam folders.
To get the best results, verify your custom domain in Omnisend and use a branded email address hosted on that domain.
Benefits
Your sender email address is what appears in the “From” field when contacts receive your emails. This is what your audience sees first, and it plays a key role in how your emails are recognized and delivered.
To use a sender email address that matches your brand (e.g., [email protected]), you first need to verify your sender domain. Once the domain is verified, you can add a branded email address from that domain as your sender address.
A verified sender email address can:
Improve inbox placement – Emails sent from your custom domain's email address are less likely to be flagged as spam.
Build brand trust – Recipients recognize and trust emails that come from your store’s domain (e.g.,
[email protected]).Meet compliance requirements – Gmail, Yahoo, and other providers require domain authentication and branded email address for bulk email sending.
Note: Sending from Omnisend’s shared domain can reduce deliverability and increase the risk of landing in spam. Always sign your custom domain before sending emails to customers.
Sender Email Address Setup Process
Step 1. Go to Store settings → Email addresses → click Add email address.
Step 2. Enter the email address you would like to use as a sender.
Step 3. Once the email is added, a verification email will be sent to your inbox to confirm the selected email.
Step 4. Check the email in your inbox and click on Verify my sender email address.
The delivery time may vary depending on your email provider. If you don’t see the email in your inbox, be sure to check your Spam and Promotions folders.
Note: If you still haven’t received the email after 30 minutes, send a message from the address you’re trying to verify to [email protected]. Our team will complete the verification manually for you.
💡 You can add multiple sender email addresses based on your use case. Each address can be verified separately by following the same verification process.
Step 5. Once your sender email address is verified, you'll be able to use it for your campaigns and automation.
In campaigns, you can manage the sender email address under Email settings.
In automations, click on the email block to manage your sender email address.
Reply-to Email Address Setup Process
The reply-to email address is where customer responses will be delivered if they choose to reply to your email. It can be the same as your sender email or a different one, depending on your preference and inbox availability.
If you don’t specify a separate reply-to email address, Omnisend will automatically use your sender email address to receive replies. However, if you prefer to use a different reply-to address, you can verify it following the same steps outlined above and then set it manually in your campaign and automation email settings.
When setting up a campaign, check the toggle next to Receive replies to a different email address and select from your verified emails.
In automations, click on the email block → check the toggle next to Receive replies to a different email address → select the email address.
Note! If you send an email using address X but set address Y as the reply-to, all customer replies will be directed to Y. When a recipient clicks “Reply,” address Y will appear in the “To” field of their response.
FAQ
What happens if I use a personal email address as the sender, like [email protected]?
Using a personal email address from a public provider (e.g., @gmail.com, @yahoo.com) is not supported in Omnisend. Emails sent from these addresses are likely to be rejected, land in spam, or fail to meet compliance standards for bulk sending.
To ensure deliverability and meet authentication requirements, use a sender email hosted on your verified domain, for example, [email protected].
What's the difference between the sender email and the reply-to email?
The sender email address is the "From" address recipients see. The reply-to email is where responses are delivered when recipients click "Reply." By default, Omnisend uses your sender email as the reply-to address, but you can also set a separate reply-to if you want replies to go to a different inbox.
Why is my sender email field greyed out in campaigns/automations?
This happens when your domain isn't verified or assigned to Campaigns/Automations. You need to first verify your custom domain, then assign it to Campaigns or Automations. Once assigned, you can select sender emails that match that domain.
How can I change the sender profile picture shown in my emails?
The profile image that appears next to your sender email address is not controlled by Omnisend. It’s managed by your email service provider, such as Google (Gmail), Microsoft (Outlook), or Yahoo.
To update this image, you’ll need to change it directly within your email service account. Learn how to change the profile picture in Gmail, Outlook, or Yahoo.
