Safety

Sending an email means handing your message to networks you do not control. Service-smtp secures the three links that matter: the transport, the authentication of your domain, and the reputation of the IPs that carry your messages.

Encrypted transport, wherever you are

The server accepts TLS (recommended) and SSL connections: your credentials and messages stay confidential, even on a shared or public connection (hotspot, hotel, trade show). Plain unencrypted mode remains available for legacy equipment.

All available ports are listed on the Flexibility page and in the technical features.

Signed, therefore delivered: SPF and DKIM

We provide the SPF and DKIM records to publish on your domain name. Once in place, every message leaves authenticated and signed: the recipients’ filters know it really comes from you, and it lands in the inbox instead of the spam folder.

Step-by-step guides walk you through it: setting up SPF and signing your messages with DKIM. Every send is then visible in your customer area history, with its delivery status.

French IPs with a monitored reputation

Our servers are hosted in France, on 100 % French IP addresses. Your emails do not transit through servers outside Europe and the service is GDPR-compliant. The reputation of these IPs has been our job since 2009: it is what makes a message land.

A verified framework for lasting deliverability

Everyone’s deliverability relies on everyone’s discipline. Our anti-spam policy is strict, and high-volume plans are reserved for verified accounts: verification is free and requested in a few clicks from your customer area. This framework protects the reputation of the IPs you share, and therefore your own sending.

To check that a server really accepts encryption and presents a valid certificate, our online SMTP test verifies it live.
