From your contacts to the right audience

1

Import contacts

In hellomateo you import contacts via CSV or, in the Business package and above, via an integration. In the setup appointment you clarify which route suits your contact data.

2

Obtain consent

The hellomateo opt-in process takes customers to sign-up via QR code or WhatsApp link. Your customer confirms consent with a button in the message.

3

Look up consent

hellomateo records consent and opt-outs in the activities on the contact. Your customer’s confirmation appears in the chat with date and time. Marketing and transactional consent are listed separately.

4

Put together an audience

In hellomateo you combine filters for contact details, existing orders and appointments. The dynamic list follows your conditions and can be selected for a campaign.

Features

Manage contacts, consent and lists

In hellomateo you find customer data and consent on the contact and use filters to put together the right recipients.

Read customer data and conversations on the contact

The hellomateo customer details view shows contact data, custom fields, chats and notes as well as existing orders and appointments; customer journeys are added in the Business package and above. For example, you open the last chat and read the note about the next workshop visit. You can also display selected custom fields in the sidebar of the inbox. This way the customer number sits next to the conversation while you reply.

  • View contact information and custom fields

  • Read chats and notes on the contact

  • Open existing orders and appointments

  • Show custom fields next to the chat

Document consent separately per channel

hellomateo keeps marketing consent and transactional consent separately for each channel. In the activities on the contact you see when marketing consent was added or withdrawn, and in the chat the confirmation with date and time. If a customer writes only “Stop” or “Stopp”, hellomateo ends the marketing opt-in for this channel and sends your stored unsubscribe confirmation. The contact is kept.

  • See marketing consent per channel

  • See transactional consent separately

  • Look up the time of WhatsApp consent

  • Record unsubscribes via “Stop” or “Stopp”

Obtain WhatsApp consent at the push of a button

Your customer confirms with a button in WhatsApp. Under “Active Subscriptions” you find the sign-ups; the report shows new and lost subscribers. This way you can follow how your sign-ups develop.

  • Provide a QR code for sign-up

  • Share a WhatsApp link for sign-up

  • Have consent confirmed with a button

Import contacts via CSV or integration

In hellomateo you import contacts from a CSV file and map the columns to the matching fields. Consent can be imported per channel in separate columns. In the Business package and above, you can connect your industry software. Which contact data, orders and appointments are transferred depends on the system. In the setup appointment you decide together with hellomateo how your contacts are imported.

With some integrations, consent can also be reported back to the industry software. You clarify the scope in the setup appointment.

  • Upload a CSV file via “Import customers”

  • Map columns to contact fields

  • Import consent per channel

  • Connect industry software in Business and above

Build audiences with dynamic lists

Dynamic lists in hellomateo put together contacts according to your filter rules. You combine contact details with conditions on existing orders or appointments, linked by “and” or “or”. This creates, for example, a list of customers with a birthday this week and a WhatsApp marketing opt-in. Lists form the basis for campaigns and, in the Business package and above, for customer journeys.

  • Filter by contact details and custom fields

  • Use orders and appointments as conditions

  • Link rules with “and” or “or”

  • Create a campaign directly from the list
