Today we’re launching Nylas Transactional Send into public beta, and it’s now available to all Nylas applications.
Transactional Send is the “other” way of sending emails from Nylas. When you use a Grant in Nylas to send an email, we send it through that user’s actual mailbox so that it gets sent from their account. This gives Send great deliverability, but you’re limited by how many emails the provider will let you send per day.
Transactional Send is a way to send 1:1 or 1:many emails from Nylas, without going through your Grant’s mailbox and without the provider limitations.
How is this different from sending emails with Nylas today?
Sending through a Grant connected mailbox When you send email using a Grant, messages are delivered from an individual user’s mailbox. This is ideal when emails need to come directly from a real person, like replying to messages, sending calendar invites, or participating in ongoing conversations.
Sending with Transactional Send Transactional Send is designed for email that doesn’t depend on a user’s mailbox. Emails are sent from a verified domain, making it a better fit for product notifications, invitations, confirmations, and other outbound emails that need to scale.
Both approaches are complementary. Grant-based sending remains the best choice when you need to send as a user. Transactional Send is the better choice when you need to send as your application.
We’ve been internally using Transactional Send for the past few months for many types of emails like:
Product invitations and onboarding messages (1:1)
Marketing and announcement emails (1:many)
Meeting summaries after a Notetaker recording (1:1)
During the Public Beta we won’t be charging for usage, which makes it the perfect opportunity to see if this works for your application.
Setting up your domain for Transactional Send.
In order to send a transactional email you’ll need to register the sender’s domain through Nylas. This can be done through the Dashboard on the new Domains tab.
From the Domains tab you’ll register your own domain (like if you wanted to send emails from your application) or your customer’s domain (like if you wanted to send emails on their behalf).
Nylas generates the TXT & MX records for you to add to the DNS records for your domain, and once you’ve added them & we’ve verified their presence, you’ll be able to start sending out Transactional emails.
Sending an email
Transactional emails can be sent using the POST /v3/domains/{domain_name}/messages/send endpoint. Sending a transactional email is structured the same as sending an email from a grant’s account, but with one major difference – you need to declare who the email is from.
curl --request POST \
--url 'https://api.us.nylas.com/v3/domains/<DOMAIN_NAME>/messages/send' \
--header 'Accept: application/json, application/gzip' \
--header 'Authorization: Bearer <NYLAS_API_KEY>' \
--header 'Content-Type: application/json' \
--data '{
"to": [{
"name": "Jane Doe",
"email": "[email protected]"
}],
"from": {
"name": "ACME Support",
"email": "[email protected]"
},
"subject": "Welcome to ACME",
"body": "Welcome to ACME! We'\''re here to help you."
}'
Your payload should include who you’re sending the email to, who you’re sending it from (like noreply@{domain_name}, and then your subject & email body
Once you submit the payload, Nylas then sends out the transactional email from that address & to your recipient.
Who is Transactional Send for?
Transactional Send is great for applications that:
Send one-off informational emails to users about an action triggered from their application (like [email protected] or [email protected])
Send marketing and sales emails (like campaigns, announcements, or outreach) directly from your application.
