When we are open
The hotline is answered around the clock, every day. Everything else is read during business hours across our delivery regions — which span UTC−6 to UTC+4, so there is rarely a working day when nobody is on.
Who reads it
New enquiries go to an engineer, not to a sales inbox. If we are not the right fit we will say so on the first reply and suggest who is.
Under attack now?
Do not wait for an email reply. Call +372 5370 2630 or message it on WhatsApp — both reach a duty analyst directly, and you do not need to be a customer.
