C3 Mailime's answer
C3 Mailime's answer
C3 Mailime is WhatsApp-first, meaning every feature is built around how messaging businesses actually operate. The 1-click 24-hour window reopen, broadcast campaigns, and template builder are all native to the platform. Unlike most tools in this category, pricing is flat with no per-contact or per-message fees on subscription plans.
C3 Mailime's answer
Respond.io, Wati, and SleekFlow all charge based on contacts or active conversations, which makes costs unpredictable as you grow. C3 Mailime uses flat pricing so your bill stays the same whether you have 100 or 10,000 contacts. You also get SLA management, CSAT, and full analytics on plans where competitors charge extra for them.
C3 Mailime's answer
mall and medium businesses with customer-facing teams who rely on WhatsApp as their main communication channel. Restaurants, retail shops, e-commerce stores, and service businesses who need their team to manage customer conversations without missing messages or switching between apps.
C3 Mailime's answer
C3 Mailime was built after seeing how businesses in the MENA region were drowning in WhatsApp messages with no proper way to manage them as a team. Every agent had their own phone, conversations got lost, and there was no visibility into what was being handled or how fast. C3 was built to fix that, starting with WhatsApp and expanding to every channel customers use.
C3 Mailime's answer
C3 Mailime is built on a modern web stack with a Ruby on Rails backend and a Vue.js frontend. It runs on cloud infrastructure and integrates natively with the WhatsApp Business API through an official provider. Native iOS and Android apps are available on the App Store and Google Play.
