Email marketing that's part of your store, not bolted on
Resend-powered email with audience targeting, first-touch attribution, abandoned cart recovery, and per-merchant sender domains.
Most stores duct-tape email marketing through a third-party tool that does not know about orders, customers, or products. The marketing tool sees email addresses. The commerce platform sees revenue. Neither sees the other clearly. Attribution becomes guesswork. Targeting becomes "everyone on the list got the same email".
Mercemur ships email as a first-class part of the commerce stack. Resend powers transactional and marketing email under your own sender domain. Audience filters target real customer groups and ordering behavior. First-touch attribution links revenue back to the campaign that drove it. Abandoned cart emails know which cart was abandoned and bring the customer back to the exact products they left behind. Transactional emails (order placed, shipped, refund) carry your branding, not "Powered by" footers.
You send fewer emails to more relevant audiences. Customers see emails that match what they actually want. Revenue per send goes up.
Why Resend
Resend is built for modern transactional and marketing email. The reasons it fits Mercemur:
Per-merchant sender domains
Each merchant gets their own sender domain instead of sharing a Mercemur-owned pool. Your deliverability is your own, your reputation is your own, your inbox placement is your own.
Built-in DKIM and SPF setup guidance
The admin walks you through the DNS records you need to set up. No external documentation hunt.
Reliable delivery infrastructure
Resend is the email infrastructure used by serious software teams. The deliverability is consistent, the API is clean, the webhook events are real time.
Transactional and marketing in one place
No need to split between two email vendors. Resend handles both.
Bounce and complaint tracking
Bounces and spam complaints flow back to Mercemur automatically and add to your suppression list. You do not send to addresses that have already rejected you.
Campaigns with real targeting
Pick an audience by:
Combine filters to get specific. "Customers in India who bought in the last 30 days and belong to the VIP group" is a real query.

Track in real time
Opens, clicks, unsubscribes, and revenue come back to the admin
Open and click tracking with first-touch attribution
Every email reports:
First-touch attribution links revenue back to the campaign. When a customer clicks an email link, then later places an order, the order surfaces the original campaign as the attribution source. See which campaigns actually drive orders, not just opens.
Abandoned cart recovery
Carts that sit untouched trigger a recovery email at intervals you configure. The email includes:
Typical sequence:
Customer abandons cart
One hour later: soft reminder ("Forgot something?")
Twenty four hours later: value-prop reminder ("Free shipping on orders over X")
Seventy two hours later: discount offer (with a configurable percentage off)
Configure the timing, copy, and discount logic per store.
Transactional emails with merchant branding
Order placed. Order shipped. Refund issued. Password reset. Account created. Every transactional email carries:
No "Powered by" footers. The customer sees your brand, not the platform.
Discount codes and auto-promotions
The same promotion engine that powers storefront discounts powers campaign-driven discount codes:
Generate codes in the campaign builder, include them in the email, track redemption back to the campaign.
Bounce and complaint handling
Bounces and complaints are tracked automatically:
Hard bounces
Add the address to the suppression list permanently
Soft bounces
Retry, then suppress after repeated failures
Complaints (customer marks as spam)
Add to suppression immediately
You do not send to addresses that have already rejected you. Your sender reputation stays healthy.
Sender domain deliverability monitoring
Per-merchant sender domains mean your deliverability is your own. Monitor:
Bounce rate
Complaint rate
Delivery rate
DKIM and SPF setup status
Anomalies (a sudden bounce-rate spike) surface in the admin so you can act before it hurts your reputation.

Frequently asked questions
Best practices for email marketing
Set up your sender domain on day one
Domain reputation takes weeks to build. Start sending under your own domain (configured with DKIM and SPF) from your first transactional email so reputation accumulates from the start.
Warm up your sender domain gradually
Going from zero sends to 50,000 sends in a day is suspicious to inbox providers. Start small. Send transactional first, then small marketing campaigns, then scale up.
Segment audiences narrowly
A blast to your entire list is the lowest-performing email you can send. A targeted send to "customers who bought a related product in the last 90 days" performs dramatically better.
Time emails to local timezones
A customer in India should receive your campaign at 10 AM IST, not 10 AM PST. Audience filters by region handle this naturally.
Keep subject lines short and specific
Generic subjects ("Big news!") get ignored. Specific subjects ("Your order has shipped, tracking inside") get opened.
Pair every campaign with a clear CTA
One CTA per email. Customers act on the email if the next step is obvious.
Honor unsubscribes immediately
Suppression is automatic in Mercemur. Do not work around it. Sending to a customer who unsubscribed damages your sender reputation and is illegal in most regions.
