Custom SMTP
Introduction
Flexopus is using a third party service to deliver email from the application to the users. These service is called an SMTP service. Using third party SMTP service for email delivery is a common practice for SaaS application.
Flexopus uses two SMTP providers to deliver the mails like: booking confirmations, check-in reminders, forgot password, booking summaries, guest invitations, welcome mails and other application specific mails. The primary SMRP service is provided by Rapidmail and the secondary SMTP service is provided by MailJet. The primary provider is sending 99.9% of the email, however due to the high amount of mails sent via Flexopus sometimes the primary SMTP service provider fails to send the mail. Therefor, we have a secondary provider to catch the failed email sending and try it again.
The SMTP providers use many IP addresses to send the mails and ensure that the IP quality is high enough to be accepted by the receiving servers. Our primary SMTP service provider Rapidmail is based in Germany, EU, the secondary SMTP provider MailJet is based in France, EU.
Custom SMTP
Even tho we have two reliable EU based providers for email sending, some customers require more customizability and wish to send the mails with their own internally used SMTP providers.
A custom SMTP provider can be configured for each Flexopus cloud application individually. This way, the email's ending is looped directly through your provider. We even offer a customizability to configure a custom primary and a custom secondary email provider of your choice. Alternatively, we can configure your SMTP service provider as a primary service and use our current primary SMTP service as your secondary to ensure a high deliverability rate.
Configuring a custom SMTP service is optional, since using suppressors such as the SMTP providers are allowed through the Data Processing Agreement (DPA). The DPA is signed between both parties due to GDPR, however in case you wish to customize it we offer a way to do so.
Configuration Manual
Configuring a custom SMTP is not included as part of the standard license agreement. The configuration and the maintenance of the configuration requires extra work load on the Flexopus, therefor you need to book this service via support@flexopus.com.
Once the module is booked, you can provide our DevOps team via support@flexopus.com the credentials to your SMTP service, such as:
host! example: smtp.example.comport example: 587username password
We recommend providing the credentials in some protected way and sending the password in a separated mail from the username. Once the credentials are provided and the module is booked, we will test the connection and finish the configuration.
