What is an Email API?
An Email API (Application Programming Interface) is a tool that allows businesses to send and receive emails programmatically, without relying on traditional email platforms. Instead of sending emails manually, companies can integrate an Email Validation API into their applications, CRMs, or websites to automate transactional emails (like order confirmations, OTPs, password resets) and promotional campaigns at scale.

Boost Your Email Deliverability with Siratel
Make sure your emails land in the inbox, not the spam folder. Siratel helps you reach customers faster, keep your lists clean, and protect your sender reputation.
Key Deliverability Features:
Email Authentication (SPF, DKIM, DMARC)
Think of this as a digital signature for your emails. Authentication proves your messages are real and secure, which builds trust with inbox providers and improves delivery rates.
Dedicated IPs
Instead of sharing space with others, you get your own IP address. This gives you full control over your sender reputation and ensures your emails aren’t affected by other senders’ mistakes.
Domain Warm-Up
Start small and gradually increase the number of emails you send. This shows inbox providers that you’re a genuine sender, helping you avoid blacklists and boosting deliverability.
Email Validation
Remove fake or inactive email addresses from your list. This keeps your database healthy and ensures your campaigns only reach real, active customers. Siratel’s system can validate up to 3 million emails per hour with accurate reports.
👉 In simple terms: Authenticate your emails, use your own IP, warm it up slowly, and clean your list regularly — that’s how you get better inbox placement and avoid being blocked.
