Deliverability optimisation
Reach the inbox, every time
Manage authentication, sender reputation and routing in one place, so the messages your customers are waiting for actually arrive.
Why deliverability needs a smarter approach
Mailbox providers have raised the bar. Gmail and Yahoo now enforce authentication, have low complaint rates and easy unsubscribe options, and judge senders on engagement in ways that shift month to month. A message that landed last year may not land today.
Managed authentication and reputation monitoring close the gaps before they cost you. Spotler SendPro watches how each domain, source and IP is performing, flags problems early, and routes around them, so deliverability is something you can rely on rather than something you firefight.
Better deliverability starts here
Strong deliverability is not a matter of luck. It is the right authentication, a clean reputation, and routing that adapts to how mailbox providers actually behave. SendPro brings those together.
Authentication
Get SPF, DKIM and DMARC right
SendPro helps you set up SPF, DKIM and DMARC for your sending domains, so you meet inbox requirements without becoming a DNS expert.
Reputation
Monitor sender reputation in real time
SendPro tracks bounces, complaints and blocklist signals, so you can act on a problem while it is still small rather than after a campaign has stalled.
Analytics
Full visibility, message by message
SendPro gives you per-message logs and clear delivery analytics, so you can trace a single email through to its outcome and fix the cause rather than guess.

Frequently asked questions
How does SendPro improve email deliverability?
SendPro manages the three things that decide deliverability: authentication, sender reputation and routing. It helps set up and validate SPF, DKIM and DMARC, monitors bounces, complaints and blocklist signals in real time, and routes mail intelligently based on how mailbox providers respond. The result is consistent inbox placement without you having to manage the underlying infrastructure.
Why are my transactional emails landing in spam?
It is usually a combination: incomplete authentication, a reputation hit from bounces or complaints, or content and routing that mailbox providers distrust. Because providers like Gmail and Yahoo now enforce stricter rules, gaps that used to be tolerated now push mail to spam. SendPro identifies which factor is at fault and addresses it, rather than leaving you to guess.
Where is my email data processed?
SendPro is hosted and owned in Europe, and your message content, recipient data and engagement data are processed within the EU. For teams with GDPR or data residency requirements, that removes the jurisdictional uncertainty that comes with US-based providers, while still giving you strong deliverability.
Do I need technical knowledge to set up authentication?
No. SendPro handles SPF, DKIM and DMARC configuration and validation for your sending domains, and flags anything that needs attention in plain terms. You get authentication that meets current Gmail and Yahoo requirements without having to manage DNS records yourself.
