How to deal with SPAM
The sending of unsolicited e-mails (commercial communications) is a relatively topical topic today. In view of the large number of such e-mails, technical solutions are emerging that seek to reduce anonymous distribution of spam. Unfortunately, these antispam tools, filters, and settings can sometimes result in trouble-free and expected email as SPAM (it always depends on the recipient's mail server's specific configuration and how it handles spam).
So if you run a reservation system from which you send (in your name / address) emails to your customers with a booking confirmation, booking notification, etc., it is good to remember that in some cases these emails may end up in SPAM. One solution that can help reduce the risk of non-delivery of e-mail messages is to use the SPF (Sender Policy Framework) configuration. By correctly setting up your domain you will tell the world (mail servers) that specific mail servers have the right to send e-mail messages on your behalf, ie with your address. Because all reenio emails are sent through a dedicated, dedicated cloud-based cloud solution, you need to make sure that emails with your address are trusted, even if they are sent from our servers.
SPF is set in the DNS configuration of your domain, ie the domain that corresponds to the e-mail address set in the system. As this is a significant intervention (incorrect settings can affect sending emails with your address), we strongly recommend to leave this setting to your IT administrator, who takes care of your domains! Within the SPF settings, it is necessary to create / edit the TXT record in the DNS settings of the domain to include the domain reenio.cz.
Example of possible (with respect to already existing settings) TXT record value
v=spf1 a mx include:_spf.google.com include:spf.smartemailing.cz include:reenio.cz ~all

SMS messages as a suitable supplement
The issue of sending e-mail messages and protecting against spam is very complex and still evolving. This will not always ensure that emails reach all recipients through all protection, filters, and security settings (especially if the recipients have email running on corporate networks and systems). That is why the reenio reservation system also offers a second form of direct communication with customers by means of SMS messages. By combining both approaches and using two communication channels (e-mail and SMS) you will be sure that all necessary information will reach your customer!
