Frequently Asked Questions

▶Which e-commerce platforms does this work with?

NumSwift works with any platform that shows you the buyer's phone number. This includes Shopify, WooCommerce, Etsy, Amazon Seller Central, eBay, and any marketplace or custom store. Simply copy the phone number from your order details and paste it in.

▶Is WhatsApp better than email for order updates?

WhatsApp messages have significantly higher open rates than email — often above 90% compared to 20-30% for email. For time-sensitive updates like delivery coordination or issue resolution, WhatsApp provides faster two-way communication.

▶Can I send order updates to international buyers?

Yes. NumSwift formats the number with the correct international country code so WhatsApp opens the right chat. This is especially useful for cross-border sellers on platforms like Etsy or eBay where buyers come from around the world.

▶Does this replace WhatsApp Business API integrations?

No — it complements them. API integrations handle automated messaging at scale, but NumSwift is for the ad-hoc messages that fall outside automation: custom delivery instructions, one-off issue resolution, or personal thank-you messages that build customer loyalty.
