Brands trusting SendPro to deliver their emails
Take away the uncertainty.
Many dev teams rely on low‑cost SMTP relays or DIY scripts only to cross their fingers and hope for the best. But that gamble carries real risks: spam catches, IP blocklisting, and dreaded greylisting. Emails that vanish into thin air, silent bounces you never even see, and support tickets piling up as frustrated users wonder, “Where’s my mail?”
Result: wasted time chasing ghost emails, broken user flows, and a reputation taking hits. Your infrastructure shouldn’t be praying for deliverability.
Built to send emails at any scale.
Whether you’re sending a handful of alerts or thousands of order confirmations per minute, SendPro scales gracefully. Unlike cheap setups that buckle under pressure, SendPro’s API-driven infrastructure adapts to your needs. It effortlessly manages both low and high volume without any developer juggling.
Plus, every email can be personalised on the fly, from inserting customer names to attaching order receipts, without added complexity. That means you can maintain a human touch, even at scale, relying on one strong API to do the heavy lifting and ensure each message lands securely in the inbox.
Start sending emails with confidence
Get startedSendPro goes where others don’t:
Authentication by API
Automate DKIM, SPF and DMARC setup via API. No guesswork.
Bounce & retry handling
Our API detects soft and hard bounces and automatically retries soft failures.
Flow & rate controls
Control sending rates and prevent ISP throttling or blocklists with flow rules.
Real‑time metrics & alerts
Get visibility into delivery statuses, bounces, opens & clicks by domain or region.
Say goodbye to DNS headaches.
Have you ever found yourself doom-scrolling through endless StackOverflow threads at 2 AM, each more cryptic than the last, as you wrestle with DKIM selectors and TXT records? With SendPro, those DNS nightmares are gone. Our onboarding manager walks you through setting up SPF, DKIM and DMARC in minutes. You don’t need to run through endless forums or beg your colleagues for help. Ultimately, your domains are authenticated, ISPs trust your mail, and you can focus on building, not bug-fixing.
Share intel with whoever needs to know.
Chasing bounced contacts? Sending emails to dead inboxes? Not on our watch. SendPro automatically flags hard bounces and syncs the info back into your source systems, so you avoid sending to bad addresses again. But that’s not all: pipe your email metrics straight into your business intelligence tools and watch delivery rates, bounce spikes and engagement trends unfold in real time.

Sending
OAuth2-powered email delivery
SendPro handles the heavy lifting so you don’t have to. With a simple POST /oauth/token to fetch an OAuth2 token, you’re ready to securely call POST /{account_id}/messages/submit and send authenticated emails. This ensures your messages are trusted—no more DNS gymnastics or token chaos, just clean, secure delivery backed by industry-standard flows.
Handling
Smart retry and flow control
SendPro gives you API-powered resilience with endpoints like GET /{account_id}/message_events, GET /message_hold, and POST /messages/{id}/resend. These let you automate retry logic for soft bounces or filter out hard bounces seamlessly. Add flow control with GET/POST/PUT /{account_id}/event_flows and /event_flow_rules, and you’re throttling, rerouting or pausing at will.
Reporting
Real-time metrics & observability
Visibility is everything. Pull data via GET /{account_id}/messagestats, GET /flows/{flow_id}/stats or inspect events with GET /{account_id}/message_events. Feed it all into Power BI, Grafana, or your own dashboard to monitor delivery rates, bounce patterns and flow efficiency in real time. When issues hit, you’ll know immediately and have the data to resolve them before tickets climb.
