Texts and voicemail
Texts
UserFinder texts a person only after you record that they agreed, what they agreed to, and how. Every text names your business. Texts go out between 9am and 8pm in the recipient's time zone. Anyone who replies STOP gets no more texts; HELP gets a reply saying who you are and how to stop.
Voicemail
Voicemails use an artificial voice and are left only for people who agreed to them. Each one names your business. Numbers that opted out are skipped.
