Sendible, founded in 2009, is the second-oldest tool in this category after Hootsuite, also covered in this directory, and differentiates on agency-specific structural details rather than a fundamentally different core mechanic: unlimited team members on every plan regardless of tier, where several competitors charge per additional seat.
Client Connect, its client-onboarding feature, lets an agency connect a client's social accounts without ever handling or storing that client's login credentials directly, alongside dedicated workspaces separating every client, brand, or location into its own organized space, addressing real agency operational friction around security and multi-client organization.
There's no free plan; pricing starts around $29 a month. For an agency that wants unlimited team seats and secure, password-free client onboarding built directly into the platform, rather than per-seat pricing and manual credential handling, Sendible's structural agency-focused features address that directly.
