These "WhatsApp credits" keep coming up. What are they and how do I get more?

Credits are your balance for sending guest WhatsApp notifications — one credit, roughly one message. You get a bundle with your paid plan: around 1,200 credits on the 100 GB plan, 3,000 on the 500 GB plan, and 12,000 on the 1 TB yearly plan. When you run low, you can buy lifetime add-on packs: 200 credits for ₹100, 1,000 for ₹500, or 2,000 for ₹1,000. Given each message costs Snaptide ₹0.85 and the packs work out cheaper than that, they're essentially selling at cost or a small loss to keep the feature useful.
