Respond.io vs Converge

Respond.io is a business messaging platform with a 4.8/5 G2 rating from roughly 302 reviews (2026), focused on helping businesses communicate with customers through messaging channels. The platform supports WhatsApp, Instagram, Messenger, Telegram, Viber, LINE, WeChat, and custom channels. Respond.io differentiates with its contact-based pricing model — you pay based on monthly active contacts rather than agent seats — and an AI agent called Respond AI that handles automated conversations.

Converge is a messaging-first inbox at $49/month flat for up to 15 agents. Both platforms target messaging-first teams, but differ on pricing model: Respond.io charges $79-$279/month based on contacts; Converge charges $49/month flat regardless of contact or conversation volume.

Respond.io's channel coverage in Asian messaging is strong: WhatsApp, Telegram, LINE, WeChat, Viber, Instagram, Messenger, SMS, and custom channels via API. The Workflows builder provides visual automation for routing, tagging, and automated responses. Respond AI handles front-line inquiries with knowledge base-trained responses. Contact merge links conversations across channels to a single customer profile. Broadcasting enables bulk WhatsApp and SMS marketing.

Discord and Zalo are not supported. The contact-based pricing means costs scale with how many unique contacts you interact with per month, not with team size. This works well for teams with many agents handling a stable customer base, but creates cost pressure for businesses with high volumes of new contacts (lead generation, e-commerce).

Converge covers WhatsApp, Telegram, Discord, Instagram, Zalo, Messenger, Gmail, and email with AI reply suggestions at $49/month flat. No contact limits, no usage-based scaling. Converge doesn't support LINE, WeChat, or Viber, and doesn't offer broadcasting or the visual Workflow builder. Channel coverage differs by region: Respond.io is stronger in East/Southeast Asia (LINE, WeChat); Converge is stronger in specific niches (Discord, Zalo).

Respond.io pricing (monthly, based on monthly active contacts):

• Starter: $79/month — 1,000 monthly active contacts, 25 users, basic features
• Growth: $159/month — 1,000 contacts (expandable), 50 users, Workflows, broadcasting
• Advanced: $279/month — 1,000 contacts (expandable), 200 users, advanced reporting, multiple workspaces
• Enterprise: custom pricing — unlimited contacts

Additional contacts cost extra per block. WhatsApp conversations incur Meta fees on top. A team with 5,000 monthly active contacts on Growth could reach $300-$400/month depending on contact pricing.

Converge: $49/month flat for up to 15 agents with unlimited contacts. For teams with high contact volumes, Converge's fixed cost advantage grows. For teams with very few contacts but many agents, Respond.io's contact-based model could be cheaper.

Choose Respond.io if you need WeChat, LINE, or Viber support alongside WhatsApp and Telegram — these are channels Converge doesn't cover. Respond.io's contact-based pricing also suits teams with many agents but relatively few active contacts, where per-seat pricing would be more expensive. The platform's Asian messaging channel coverage (LINE, WeChat, Viber) is particularly strong.

Choose Converge if you want predictable flat pricing regardless of contact volume, need Discord or Zalo support, or your contact volume is high enough that respond.io's contact-based pricing becomes expensive. Converge at $49/month has no contact limits.

Choose Respond.io if: You need WeChat, LINE, or Viber support for Asian markets. You have many agents but few monthly active contacts (where contact-based pricing beats per-seat). You want WhatsApp broadcasting for marketing outreach. The visual Workflow builder fits your automation needs.

Choose Converge if: You want flat $49/month pricing regardless of contact volume. You need Discord or Zalo support. Your business has high contact volume (e-commerce, lead gen) where contact-based pricing becomes expensive. You prefer predictable costs over usage-based scaling.
