Questions, answered
Everything you need to know before your first send.
Can I send personalized SMS from Excel or CSV?+
Yes. Upload an XLSX or CSV file, choose the phone-number column, and insert any other column into your message. ZukaOS shows the personalized results before you send now or schedule them for later.
How much does ZukaOS SMS cost?+
SMS pricing starts as low as 0.03 per message, so you can scale customer communication without committing to a large monthly plan.
Do my credits expire?+

Can I schedule SMS campaigns?+
Yes. Schedule one-time messages, reminders, and customer follow-ups from the workspace, then review their status in message history.
Is there an SMS API?+
Yes. ZukaOS SMS includes developer tools and API tokens so your product, CRM, or internal workflow can trigger messages programmatically.
Can I automate birthday wishes and reminders?+
Yes. The Birthday App can send a personalized birthday wish to matching contacts or send an advance birthday list to you and selected recipients. Choose all contacts or a contact group, set the delivery time, and include contact fields such as name and custom fields.
Who is the Birthday App for?+
It is useful for churches and faith communities, social and community organizations, gyms and clubs, membership groups, schools, and customer care teams that want to make people feel remembered.
