Complete Sending Infrastructure
Move email delivery out of the application server
Give every application a secure sending channel while your team controls domains, credentials, usage and delivery from one customer-isolated portal.
Multiple domains per customer
Verify and operate several sending domains with separate SMTP credentials, logs, quotas and authentication status.
Guided DNS authentication
Publish ownership, SPF, DKIM and DMARC records manually or use safe Cloudflare automation with conflict previews.
Complete delivery lifecycle
See queued, processing, delivered, deferred, bounced, failed and suppressed outcomes with useful SMTP diagnostics.
Reports and integrations
Export recipient-level delivery reports or send restricted, HMAC-signed status events to customer systems.
Reputation protection
Stop repeated sends to invalid or suppressed recipients and monitor authentication alignment and delivery issues.
From Signup to First Send
A clear path to authenticated email
The portal guides customers through the controls that receiving mail systems expect.
Add and verify a domain
Copy the required records or connect Cloudflare, preview the changes and publish only safe updates.
Create secure credentials
Generate SMTP credentials or scoped API keys. Secrets are shown once and can be rotated or revoked.
Send, monitor and improve
Track delivery, export reports, receive signed webhooks and remove invalid recipients from future sends.

Know What Happened
Useful delivery evidence for operations, accounts and support
See when a recipient mail server accepted a message, identify mailbox-not-found responses and investigate temporary delivery problems without searching raw server logs.
Clear and accurate: a delivered status confirms acceptance by the recipient mail server. It does not claim that a person opened or read the email.
Common Questions
Frequently Asked Questions
Everything you need to know about setting up MailOps.
Can one customer use multiple domains? +
Yes. Domain and credential limits depend on the selected plan, and each customer’s data remains isolated.
Will my current application work? +
Most systems that support authenticated SMTP over TLS can connect without custom development. A REST API is also available.
Can DNS records be added automatically? +
Cloudflare zones can use a guided automation flow with a preview before changes are applied. Copy-ready records are provided for other DNS providers.
Can customers receive delivery updates in their own system? +
Yes. Signed HTTPS webhooks and recipient-report APIs provide restricted delivery metadata without exposing message content or subject lines.
How does South African billing & SARS VAT work? +
MailOps provides official tax invoices on the 1st of every month with 15% VAT and 7-day grace period protection. We accept Instant EFT, Credit Card, and bank transfers.
