Why T28X Uses MailerSend for Transactional Emails
When you run a company like T28X, marketing emails and transactional emails serve two different missions. Marketing emails are about relationships and growth. Transactional emails are about trust and reliability. That’s why I use MailerSend for all transactional communication: invoices, confirmations, receipts, account notifications.
The Difference Between Marketing and Transactional Emails
A promotional campaign landing in spam is annoying. A receipt or password reset going missing is a disaster. That’s the real difference. Transactional emails must arrive — no excuses.

Why MailerSend?
MailerSend is designed for developers and businesses that care about deliverability at scale. For me, these features stood out:
- SMTP relay and API options: Flexible for different systems.
- Real-time analytics: See delivery success, bounces, or spam flags.
- Dynamic templates: Reusable designs for receipts, order updates, or confirmations.
How It Helps T28X
T28X manages multiple sites and brands. MailerSend supports multiple domains, making it easy to keep transactional messages professional, branded, and reliable.
It also means my customers never wonder if an order went through or if an account update worked. That reliability builds confidence in every interaction, which matters more than any flashy campaign.
Deliverability Built-In
MailerSend doesn’t just send messages. It makes sure they’re authenticated and safe. With SPF, DKIM, and DMARC support, it keeps messages out of spam folders and in inboxes where they belong.
For a business built on trust, that’s non-negotiable.
