A site that is in Seravo upkeep can have one or multiple contact persons for technical matters. The contact emails can be managed via the WordPress dashboard under Tools -> Upkeep
As the site owner you should make sure that the information is up to date. You can add multiple emails to the contact list so you should always add the emails of your digital agency partner, site developer etc. to make sure that the correct people are informed.
We send all kind of information regarding the site to the technical contacts. We might contact you because of some problem in the PHP code in the site, about some plugin compatibility issue or if there is a security issue that has been caught our monitoring.
We use the word Technical Contact as the client often has different contacts for billing related communication.
