Deliverability isn't a feature — it's the foundation. Every email you send through IGSendMail is backed by enterprise-grade authentication, dedicated infrastructure, and proactive reputation monitoring.
Most email platforms use shared sending infrastructure. When one user on the shared IP sends spam, everyone's deliverability suffers. Your carefully crafted campaign lands in spam because of someone else's bad practices. IGSendMail solves this with dedicated infrastructure and proactive monitoring.
Six layers of protection between your email and the spam folder.
Your sending reputation is yours alone. Professional plans include a dedicated IP — no sharing, no contamination. Additional IPs for $25/month.
Automated SPF, DKIM, and DMARC setup with step-by-step verification. We guide you through it and confirm it's working correctly.
Hard bounces removed immediately. Soft bounces retried with exponential backoff, then removed. Your list stays clean automatically.
Registered with all major ISP feedback loops. When a recipient marks you as spam, we instantly unsubscribe them — protecting your reputation.
Real-time monitoring across major blacklists. If an issue is detected, you're alerted immediately with specific remediation steps.
Built-in email verification flags invalid, risky, and disposable addresses before you send. Clean lists mean higher inbox rates.
Three layers of proof that you are who you say you are.
Tells receiving servers which IPs are authorized to send email for your domain. If the IP matches, you pass.
Adds a cryptographic signature to every email, proving it hasn't been tampered with in transit. The receiving server verifies the signature against your public key.
Ties SPF and DKIM together. Tells receiving servers what to do if either fails — quarantine, reject, or report. Completes the trust chain.
IGSendMail configures all three automatically when you verify your domain. Most users are fully authenticated in under 10 minutes.
Measured averages across all IGSendMail customers, updated monthly.
Our built-in spam score checker analyzes your email content, subject line, authentication, and sending reputation before you hit send — catching issues that would land you in spam.
