Data we collect

Mailing Lists
If you have opted-in to receive our email updates, this means we have collected your personal information. We do this in order to contact you by email about activities and events that we believe you will be interested in. We don’t rent or trade email lists with other organisations and businesses. We use a third-party system provided by Zoho Corporation to store the information you provide (Zoho CRM) and to email you (Zoho Campaigns). Through this we will gather statistics around email opening and clicks using industry standard technologies to help us monitor and improve our e-newsletter. You can unsubscribe to general mailings at any time of the day or night by contacting

If you are a member of METREX we collect additional information you provide to us about you and the organisation you represent within METREX. We collect this additional data – such as contact details, biography, organisation and job title – to enhance networking capabilities across the organisation and to connect you with relevant activities. If have previously been invited to join as a member, or have resigned as a member, we retain limited data to ensure we have a record of this so that we don’t waste your time with future invitations. This includes your name, organisation, job title and date of contact / membership. We use third-party systems provided by Zoho Corporation (Zoho CRM) and Microsoft (Sharepoint) to store the information you provide. For more information please contact

Personal identifiable information]
Occasionally for events with increased security we need to request information such as passport or ID details. Only the minimum required information will be requested. This information will be shared only with the services that need it in order for the event or activity to take place as planned. For example, events in the European Parliament require advanced authorisation of all delegates, including passport or ID details, date of birth, etc. METREX will not hold such information beyond the date that is necessary.

When you register your attendance at a METREX event, the details that you submit will be retained for the purposes of logging your interaction with our network. This helps us tailor future events according to who has attended previous events.

Data storage
Data is stored in these locations:

  • Microsoft Sharepoint – (METREX data storage)
  • Interxion Frankfurt – part of DE-CIX (website server)
  • Zoho CRM and Zoho Campaigns (contact database / Email Campaigns)
