Deliverability & Security

Our own gateways, proven reputation and award-winning security standards make sure your emails aren't just sent but actually seen.

The challenge: Firewalls & security gateways

Firewalls and security gateways check every email before it arrives.

A message that shows as delivered in your campaign reporting can still end up in quarantine on the receiving server, without ever showing up in your own metrics.

Security gateways on the recipient side

Many companies place their own security gateways in front of the inbox as an additional check of every incoming email, independent of the mail provider.

Not a bounce... but covert quarantine

Emails classified as suspicious may not be rejected but held back, without returning an error message. You'll never know.

A blind spot in your own statistics

The dispatch report shows “delivered”, whether the email actually landed in the recipient's inbox or not.

Deliverability as a service component

Deliverability doesn't happen by accident. It is the result of the right infrastructure, certification, and consistent reputation maintenance.
