All-in-one platform for every email you send

No need to juggle multiple services. While your transactional emails run in the background, use the same platform – built for teams, including developers, SaaS teams, and ecommerce stores – to design and send marketing campaigns.

High-priority service emails

Send time-sensitive emails with zero delays

Sender makes sure password resets, one-time passcodes (OTPs), and account confirmations land in inboxes in real time. Track every send and monitor transactional delivery in real time from your logs.

Email security and deliverability

Protect your reputation with built-in security

Strong deliverability starts with authentication. Set up SPF, DKIM, and DMARC on your sending domain, then Sender handles the rest so your transactional email stays out of spam folders.

Frequently Asked Questions

1.

What is a transactional email?

A transactional email is an automated message sent to one person in response to an action. Think order confirmations, shipping updates, password resets, and one-time passcodes.

2.

What is the difference between transactional and marketing email?

Transactional emails are triggered by a user's action and sent individually; marketing emails are promotional and sent in bulk. Receipts and password resets are transactional, while newsletters are marketing.

3.

Does Sender offer a free transactional email plan?

Yes, Sender's free plan lets you send transactional emails. Transactional and marketing email share one account, allowing you to send up to 15,000 monthly emails.

4.

Should I send transactional email over SMTP or an API?

Both SMTP and API are good for transactional purposes. The REST API suits developers wanting programmatic control and dynamic variables; SMTP relay is fastest when your app already supports SMTP. Sender supports both on every plan.

5.

What do I need to set up before sending?

To set up transactional sending, verify your sending domain and configure SPF, DKIM, and DMARC so mailbox providers trust your messages. Your 'from' address must match the verified domain. No IP warm-up is required on shared IPs.
