How to customize your email sender domain

Your email sender domain determines whether referral and affiliate emails land in the inbox and whether recipients trust them. Emails sent from a shared, generic address are far more likely to be flagged as spam. Customizing the sender domain means Bloop sends emails from a domain you authenticate — messages come from your brand and inbox providers recognize them as legitimate. Add your domain in Bloop, copy the DNS records it provides (DKIM, SPF, and related entries) into your DNS provider, then verify.

This page covers the three email-sender settings on Settings → General: the sender name, the sender address, and the sender domain.

Best practice

Use a dedicated subdomain (marketing.yourstore.com), not your root domain — this isolates bulk mail from the reputation of your invoice/order-confirmation domain. Add all DNS records exactly as listed and wait for propagation before verifying.

Sender name

The sender name is the “from” name recipients see in their inbox. A new store starts with the name Bloop-referral, not your store name, until you change it. Type a new name and save; no verification is needed. Editing needs a plan that includes email sender customization (Premium): on the Free plan the whole Email sender card is locked, and a banner offers a Contact us link instead.

Sender address and verification

The sender address is your store’s contact address for program emails, and where customer replies go. A new store starts with Bloop’s no-reply address, so set your own to receive replies. Bloop verifies the address before it goes live:

1. Enter the new sender address in Email sender address.
2. Select Verify, which appears once the address differs from the saved one. Bloop emails a confirmation to that address.
3. Open the email and complete verification within 20 minutes, when the link expires.

The field shows Verified or Unverified next to it. Resending the confirmation is rate-limited to once every 30 seconds. You cannot save the settings while the address is unverified.

Understanding where your emails come from

Inbox providers check that an email really comes from the domain in its From address. An email that shows your store’s address but is sent by Bloop fails that check and is likely to land in spam. So the From address depends on whether you have verified your own sender domain:

Your sender domain	From address	Where replies go
The default, email-bsscommerce.com	Bloop’s own sending address, shown with your sender name	Your sender address, set as the Reply-To
Your own verified domain	Your sender address, when it is on that domain; otherwise no-reply@ your domain	Your sender address, when it differs from the From address

Either way, customers see your sender name in their inbox, and when they reply, the reply reaches your sender address. To have emails sent from your own address, verify your own domain below.

Sender domain and DNS records

The sender domain is the part after the @. The default is email-bsscommerce.com. Setting your own domain authenticates your mail with DKIM and SPF records so inbox providers trust it. Use the Customize link next to Email sender domain in the Email sender card to open the domain setup modal:

Step	What happens
Enter domain	Type the domain (a subdomain like marketing.yourstore.com is recommended). Bloop checks whether it already exists. A domain that another store has already verified cannot be added: the field says so and links to support.
Add domain	Bloop registers the domain and returns the DNS records you must add.
DNS setup	A table lists each record (SPF and DKIM, plus any MX, CNAME or DMARC entries) with the type, name, and value to copy. Where your DNS provider adds the root domain to the name automatically, use the short name shown under each record.
Verify	After adding the records at your DNS provider, Bloop re-checks them.
Active	Once the records resolve, the domain is verified and used for sending.

Add the DNS records

1. Copy the records Bloop shows in the table (each has a copy button).
2. Log in to your DNS hosting provider.
3. Open the DNS control panel and add each record exactly as listed.
4. Save the records.
5. Wait for DNS propagation (typically 24–48 hours), then return and verify.

When the domain turns active, the domain field on the card updates, but the change only takes effect once you Save the settings.

Note

A custom sender domain is a premium feature on paid plans. If your plan changes to one without it, Bloop reverts the sender domain to email-bsscommerce.com. The sender name stays as you saved it.
