An SMTP relay you can see inside.
Point any application at SMTP2U and get the delivery events, logs and metrics that a plain SMTP server never gave you.
Four fields and you are sending.
Works with WordPress, WooCommerce, Laravel, Django, Rails, Nodemailer, PHPMailer, CRMs, ERPs, printers and anything else with an SMTP settings screen.
- Implicit TLS on 465 and 2465, STARTTLS on 587 and 2587
- Your API key is the password, and you can revoke it at any time
- Keys can be restricted to a single sending domain
- Up to 50 recipients and 10 MB per message
- Same queue, quota and suppression list as the API
# Any system that speaks SMTP: CRM, store, website, ERP. Host smtp.smtp2u.com Port 465 (SSL/TLS) or 587 (STARTTLS) alternatives: 2465 and 2587 Username smtp2u Password your API key (nm_…) # The sender must be on a domain verified in your workspace. # Attachments up to 10 MB. Everything shows up in Emails, Logs # and Metrics, with opens and clicks, just like the API.
Everything your old relay kept to itself.
Every message, searchable
Find any email by recipient, subject, status or key. Open it to see the HTML, the text and the original source.
Delivery events
Delivered, opened, clicked, bounced and complained, in the dashboard and pushed to your webhooks.
Authenticated by default
DKIM, SPF and a return path on your own domain, verified before the first message leaves.
Suppression that protects you
Addresses that bounced or complained are refused with a clear 550 reply instead of hurting your reputation again.
Logs you can read
Each SMTP session is logged next to your API requests, with the answer your application received.
One set of numbers
API and SMTP traffic share the same metrics, so the delivery rate you see is the whole picture.
Swap the host.
Keep the rest.
Most migrations are a settings change, not a code change.
