Email hello@hipereach.com with "Brand partnership" and your brand name in the subject line, or reply to your most recent weekly summary. The person who writes that summary is the one who answers, so you won't have to explain the campaign from the beginning.
You get a written reply within two business days; the mailbox is read Monday to Friday, 09:00 to 18:00 (CET). Anything that affects a live campaign comes first. If you ask us to pause an ad, take out a claim or stop spending in a country, we make that change before we discuss it.
When the problem is about numbers, we pull the platform data for the dates in question, set it against your records and our internal change log, and send you the comparison line by line. If the mistake was ours, the reply says so and says what we changed. A difference that affects what you owe is settled in the monthly reconciliation.
Some problems are about how we work rather than about one campaign. Tell us early and plainly. If it cannot be fixed, either side can end the engagement under the notice terms in the agreement.
