One square for every address.

We built Favotrip's complete B2B outreach system.

Favotrip sells trips as staff gifts. An employer sets a budget per employee, from €50 to €250, and each employee chooses a trip within the range that budget offers.

The system approaches every Dutch company with 5 to 250 employees. For each one it finds the right person, and every message is written for that company, with copy the Favotrip team reviews before anything goes out.

Business to business

Outreach systems

For companies that sell to companies. We run the whole chain ourselves, so nothing gets lost between the list, the inbox and your sales team.

Optional: an AI assistant on your landing page that answers questions about your offer and hands over to a person when needed.

  1. Map the market

    Region, sector and company size agreed with you. Every company that fits, from sources whose terms allow it.

  2. Find the decision-maker

    The person who can say yes, with their role and where we found them.

  3. Verify the address

    Checked before it enters a sequence, with the evidence kept.

  4. Research and write

    Every message starts from what we know about that company. When there is nothing worth saying, we keep it plain.

  5. You approve

    The copy and every claim, before anything goes out in your name.

  6. Send from your domains

    Mailboxes and domains in your name, warmed up gradually, with a daily limit per mailbox.

  7. Handle every reply

    A reply stops the sequence. Interest goes straight to your sales team.

  8. Attribute the results

    From sent to reply, meeting, trial and first payment, so you can see which messages produce customers.

  9. Keep customers active

    Account management after the sale: personal follow-up based on how customers use your product.

How we work

One milestone at a time.

Every engagement is split into clearly defined milestones. Each has a fixed scope, a fixed price and one decision at the end. You only ever say yes to the next step.

  1. Milestone 01

    Set-up

    We build the system, the first list and the sending infrastructure in your name. You approve the copy.

    01 / Set-up Decision: go live

  2. Milestone 02

    Pilot

    One region, a weekly volume and a weekly report, measured against figures we agree before we start.

    02 / Pilot Decision: go or no-go

  3. Milestone 03

    Scale

    More regions or segments. If you want to run it yourself, we train your team and stay on as back-up.

    03 / Scale Decision: per region

  4. Milestone 04

    Account management

    Winning a customer is step one. Step two is making sure they use you as much as possible.

    04 / Accounts Decision: per step

How we send

Deliverability is part of the product.

Outreach only works when it lands in the inbox and treats people fairly. Every programme we run meets these standards.

Sending domains
Separate domains and mailboxes in the client's name, never shared between clients.
Warm-up
Volume grows on a schedule, with a daily cap per mailbox.
Authentication
SPF, DKIM and DMARC checked for every domain before the first send.
Unsubscribe
One click (RFC 8058), processed straight away.
Opt-out list
One global list, checked before every send.
Complaints
Alert at 0.1%, automatic stop at 0.3%.
Data
Source, date and lawful basis stored for every lead. Objections are honoured for good.
Ownership
Domains, lists, sequences and reply data belong to the client and are handed over in full at the end.
