Billbooks is built to help you send invoices and get paid, not to send spam. We take a strict, no-nonsense approach to unsolicited email across everything we do.
The emails you receive from Billbooks are either transactional or marketing, and the difference matters.
Transactional email is part of the service: your invoices, payment reminders, receipts and account notifications. These go to you because you use Billbooks.
Marketing email is a short monthly note about getting paid, and a small number of follow up emails after you use one of our free tools or templates. You get these because you gave us your email address on billbooks.com, either by asking for them or by using a tool that needed an address to send you your document. We never add an address we were not given directly, we never buy or rent lists, and we do not send you more than one marketing email in a week.
Every marketing email carries an unsubscribe link, and most email apps also show their own unsubscribe button beside our name. One click stops all of it immediately, not just the message you clicked from, and it never affects your invoices or your account.
The email addresses you add for your clients are used only to deliver the invoices, quotes, estimates, and reminders you choose to send. We never sell, rent, or share your clients’ contact details, and we never email them on our own behalf.
We do not buy, sell, or use purchased or harvested email lists, and we ask that you do not use Billbooks to send invoices or messages to people who have not agreed to hear from you.
If you ever receive an email that appears to come from Billbooks but looks like spam or a phishing attempt, please do not click any links in it, and report it to our support team so we can investigate.
For anything related to this policy or how we handle email, reach out to our support team at any time. We’re happy to help.
