SleekFlow puts WhatsApp, Instagram, Messenger, TikTok, SMS, Telegram, Viber, email and calls in one shared inbox, with AI agents, broadcasts and a flow builder. Few tools here cover as many channels. The catch is the price: broadcasts start on Pro at $109 a month billed yearly for 500 active contacts, and the bill grows with every 100 more. - **Value for money: D.** Broadcasts start on Pro at $109 a month billed yearly for 500 active contacts, and each extra 100 is $20, so messaging 1,000 customers a month comes to $209. That's near the dear end even against its WhatsApp rivals, and the $15 WhatsApp number fee and message charges come on top. - **Free plan and trial: C.** No free plan, but a 7-day free trial of Pro with 500 monthly active contacts and no credit card. Short, but enough to plug in a channel and look around. - **Features: B.** The whole job across more channels than anything else here: WhatsApp, Instagram, Messenger, TikTok, SMS, Telegram, Viber, email and calls, plus AI agents, broadcasts, a flow builder and contact records with lifecycle stages. - **Ease of use: C.** No App Store rating on record. Each channel needs connecting, then there are flows and AI agents to build, and an active-contact count to watch. - **Platforms and integrations: B.** Web, iPhone and Android, with Shopify, Zapier, Make and API access from Pro, and Stripe payment links. HubSpot and Zoho start on Premium and Salesforce on Enterprise, and there's no desktop app, which an A needs. These are ToolGPA's own grades.

The category's chart of price against score: https://toolgpa.com/charts/chat-marketing ## Keep it, or make your own? **Keep it.** To replace SleekFlow you would be making the WhatsApp Business API, which Meta opens only through approved partners. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 6 of the 14 other SMS and chat marketing tools grade higher. It costs $588 a year. - You could not: The WhatsApp Business API, which Meta opens only through approved partners. - You could not: One mailbox that several people work at once. - You could not: An AI model answering your customers from your own help articles. - You could not: Email sent in volume that still reaches the inbox. - You could not: A real app for iOS and Android. Something home-made would be a web page. - You could not: It plugs into other products, Shopify, HubSpot and Salesforce among them, and has an API. - You could not: The depth: we grade its features B, which means it covers the whole job.
