Frequently Asked Questions

Emitlo supports both REST API (POST /api/v1/messages) and SMTP relay. Both protocols share the same rate limits, authentication, and observability — you can switch between them at any time without changing your domain setup. The REST API is recommended for new applications, while SMTP is ideal for existing codebases using Nodemailer, PHPMailer, Django, or Laravel Mail. Emitlo is compatible with any language or framework that can make HTTP requests or connect via SMTP.

When you add a sending domain, Emitlo automatically generates a unique RSA 2048-bit DKIM keypair and publishes the required DNS records. Verification is fully automated and typically completes within 60 seconds. Emitlo also validates your SPF record and checks your DMARC policy, providing recommendations if anything needs adjustment. Every email is signed with double DKIM — your domain key plus Emitlo's platform key — for maximum inbox placement.

Yes. Emitlo is built with GDPR compliance as a core principle, not an afterthought. Email body content is stored only during queue transit and cleared immediately after the message is submitted to the delivery infrastructure — it is never written to a long-term database. Only metadata is retained: recipient address, delivery status, event timestamps, and bounce/complaint data. Infrastructure is hosted in Europe, and a Data Processing Agreement (DPA) is available on request.

Emitlo processes bounces automatically via DSN (Delivery Status Notification) parsing with VERP-encoded Return-Path for precise per-message attribution. Hard bounces (permanent failures like invalid addresses) are immediately added to your suppression list and will never be emailed again. Soft bounces (temporary failures like a full mailbox) are retried with exponential backoff. You receive real-time webhook notifications for every bounce event, and bounce rates are visible in your deliverability dashboard.

Yes. Dedicated sending IPs are available as an add-on for senders who want full control over their IP reputation. By default, all accounts use Emitlo's high-quality shared IP pools, which are carefully managed to maintain strong deliverability. Dedicated IPs are recommended for senders with consistent volume above 50,000 emails/month who want to isolate their reputation. Emitlo includes a built-in IP warmup scheduler for dedicated IP plans.

The free plan includes 12,000 emails per month (400 emails/day cap) with no credit card required and no expiration date. It includes full SMTP and REST API access, double DKIM signing, SPF/DKIM/DMARC auto-configuration, real-time deliverability dashboard, automatic bounce and complaint handling, webhooks for all events, 3 sending domains, 3 API/SMTP credentials, and 14 days of log history. The free plan is designed for production use, not just testing.

Emitlo uses a simple pay-as-you-go model: $0.15 per 1,000 emails on the Pro plan, with no monthly commitment, no tiers, and no hidden fees. You only pay for what you send. There are no overage charges — if you send more than expected, you simply pay the same rate. The free plan covers 12,000 emails/month permanently. Pricing is transparent and predictable: at 100,000 emails/month, you pay $15.

Most teams complete the full setup — domain verification, DNS configuration, credential generation, and first email sent — in under 10 minutes. There is no sandbox to exit, no manual review process, and no sales call required. Add your domain, Emitlo publishes DNS records automatically, generate your API key or SMTP credentials, and you're ready to send. The onboarding is designed to be self-serve from start to finish.
