Getting Started with JetEmail SMTP Service

Follow these steps to set up and start using our SMTP service. Add your sending domain first, then create SMTP credentials and configure your mail server.

​
1. Add your sending domain

Each address you send from must belong to a domain JetEmail can authenticate.
  1. Log in to the JetEmail dashboard at https://dash.jetemail.com
  2. Go to Outbound → Domains. You’ll land on the Domains overview—add a domain and track DNS verification from here:
Domain overview
  1. Add the domain you send mail from (e.g. example.com)
  2. Add every DNS record the dashboard lists for that domain (SPF, return-path, DKIM, DMARC, feedback, etc.) at your DNS provider
  3. Wait until the dashboard shows the domain as verified
The dashboard always shows the exact hostnames and values to use. For a full breakdown of those records, see Email authentication. SMTP “allow any domain”: If your account uses SMTP with allow any domain, you can send without adding the domain in the dashboard, but you must still publish SPF for each sending domain (see SMTP allow any domain). Adding and verifying the domain in the dashboard is still recommended for deliverability (DKIM signing, aligned return path) and for dashboard-only features below.

​
Domain validation

A domain counts as validated after you add it under Outbound → Domains and JetEmail verifies your DNS. Validated domains are required for open tracking, click tracking, BCC copies, and similar features that depend on dashboard-managed authentication.

​
2. Create an SMTP User

Create Smarthost
  1. In the dashboard, go to Outbound → SMTP
  2. Click Create SMTP
  3. Fill in the required details:
    • Username: Choose a unique username
    • Password: Set a strong password
    • Description: Optional reference label
    • Quota / Usage: 0 for unlimited, or a limit on how many messages this user can send

3. Configure Your Mail Server

Use these values in your mail server or application:
SettingValue
Serverrelay.jetsmtp.net
Ports25, 587, 2525 — STARTTLS · 465 — SSL/TLS
AuthenticationPLAIN
TLSRequired on 25, 587, and 2525 (STARTTLS). Implicit on 465 (SSL/TLS).
Username / passwordThe SMTP user you created in step 2
EU Region Endpoint If you need to use an EU-only endpoint, you can use relay-eu.jetsmtp.net instead. This endpoint uses the same settings as above but is limited to the EU region only. The global endpoint (relay.jetsmtp.net) is our recommended anycast endpoint that provides optimal routing worldwide.
