The distinction that matters here is whether a client can review and approve content without ever holding a login to the tool itself.
HeyOrca: external stakeholders review via a link, no account required; approved by design, since Free tier even includes it (though reports/inbox/listening are separate add-ons starting at Basic).
Sendible: Client Connect lets clients securely connect their own social accounts to the agency’s Sendible workspace without sharing passwords — but this, along with approvals generally, only starts at the Plus tier ($99/mo), not the entry Core tier ($29/mo).
More tools where approval is the whole point
- RecurPost — link-based client onboarding (clients connect accounts via a share link, no credentials) and approvals included; Agency $79/mo for 20 profiles. Same team as this site — disclosure on its profile
- OneUp — approvals and password-free client links both start at Intermediate ($60/mo)
- Sked Social — no-login client portals bundled in only at Accelerate ($166/mo); Grow makes you pay approvals as separate add-ons ($500–1,000/yr)
- eclincher — approvals require jumping to Professional ($349/mo); Standard caps you at one brand
- Onlypult — content approval and role assignment start at its SMM tier ($35/mo), the cheapest entry point on this list
- ContentStudio — approval workflow and inbox start at Advanced ($69/mo)
- Postfity — external client approval starts at Growth ($85/mo)
- Social Champ — multi-layer approval starts at Professional ($59/mo)
- Statusbrew — approvals bundle with listening and sentiment analysis, but only from Premium ($299/mo) up
