Email has been the backbone of customer support for decades, but WhatsApp is quickly changing what customers expect. Neither is strictly better, they suit different jobs. Here is how they compare.
Speed and open rates
WhatsApp messages are typically opened within minutes and replied to quickly. Email often sits unread and invites long, delayed back-and-forth. For anything time-sensitive, WhatsApp wins on pace.
Tone and effort
Email feels formal and high-effort for a customer. WhatsApp feels like a quick chat, so customers are more willing to start one, and more forgiving of short replies. That lowers the barrier to reaching out.
Where email still fits
Email is still better for long, detailed records, attachments, and formal communication like invoices or legal notices. Many teams keep email for those, and move day-to-day support to WhatsApp.
Key takeaways
WhatsApp wins on speed, open rates and low customer effort.
Email still fits long records, attachments and formal messages.
Most teams use both, WhatsApp for fast support, email for formal.
Running WhatsApp support well
To handle WhatsApp support as a team, you need a shared inbox on the official API, not a single phone. Book a demo to see it in action.
