Frequently asked questions
Answers before you get started.
Need something specific? Send us your requirements and our team can clarify the scope.
Ask a QuestionWhat does “under 1% bounce rate” mean?
We manually research and verify email addresses, targeting a bounce rate under 1%. Actual campaign results may vary depending on list age, sender practices and external email systems. This is not a 100% guarantee.
How quickly can we receive a list?
Small orders can be delivered within one day. Larger lists and complex targeting depend on the agreed scope and schedule.
Where does your lead data come from?
Our team manually researches publicly available business information and verifies work email addresses. We do not claim access to private contact databases.
What if we need revisions?
Free revisions are included to bring the list into line with the agreed targeting requirements.
What formats will we receive?
We deliver Excel or CSV files with clearly labeled columns. Lists can be used in workflows involving Mailchimp and HubSpot.
Is there a minimum order?
Tell us your intended lead volume, even for a smaller list. We will confirm what can be delivered and quote your specific project.
How do GDPR and CAN-SPAM apply?
Lists are researched from publicly available business information. You are responsible for establishing a lawful basis for outreach and complying with GDPR, CAN-SPAM and other applicable privacy, marketing and local laws.
