Use a voicemail-to-text or voicemail drop service
Send a voice note through a messaging app if the recipient accepts it as a voicemail alternative
Record an audio message and email it if the recipient checks email for messages
Use a call-through service that lets you record and send a voicemail without directly calling the person
Leave a voicemail through a business phone system or virtual phone app that supports voicemail drop
Ask the recipient’s carrier or phone app provider whether voicemail can be deposited without a live call
Use a third-party voicemail drop platform if you have permission to contact the recipient
