PostOnce vs Sendible: Do You Really Need an Agency Tool?

Sendible is a well-regarded social media management platform, particularly popular with agencies and marketing teams in the UK. It's packed with features for managing multiple clients, generating branded reports, and keeping everything organised across large teams.

But here's the thing: most of those features are designed for agencies billing clients by the hour. If you're a solo creator, freelancer, or small business owner, Sendible's feature set — and its price tag — might be more than you actually need.

Pricing: agency budgets vs creator budgets

Sendible's cheapest plan (Creator) starts at $29 per month for 6 social profiles. Their Traction plan jumps to $89 per month for 24 profiles, and their Scale plan hits $199 per month.

That per-profile pricing adds up quickly. If you're running accounts across 8 platforms, you'll need the Traction plan at minimum — and that's nearly $90 per month before you've added a single team member.

PostOnce takes a simpler approach. The Solo plan gives you 10 social accounts for €12 per month. No per-profile surcharges, no hidden costs. If you need more, the Pro plan offers unlimited accounts for €25 per month.

For a solo creator posting across Instagram, TikTok, YouTube, and a few other platforms, you'd save roughly €60–70 per month compared to Sendible's equivalent setup.

Platform support

Both tools cover the major social platforms. Sendible supports Instagram, TikTok, YouTube, Facebook, Pinterest, LinkedIn, X, and Google Business Profile.

PostOnce supports those same platforms (minus Google Business for now) and adds Bluesky — which Sendible doesn't currently offer. If you're active on Bluesky, that's a meaningful difference.

Features compared

Where Sendible genuinely excels

Sendible is purpose-built for agencies, and it shows. Credit where it's due — there are several things Sendible does that PostOnce simply doesn't.

Client dashboards are probably Sendible's strongest selling point. If you manage social media for multiple clients, you can give each one a branded dashboard to review content, approve posts, and see reporting. That's a genuinely useful workflow for agencies.

White-label reporting lets you generate custom-branded PDF reports with your agency's logo and colours. For agencies that need to present professional reports to clients each month, this saves a lot of manual work.

CRM integrations connect Sendible with tools like Salesforce and HubSpot, which matters for agencies that tie social media activity back to sales pipelines. Sendible also offers a unified social inbox for managing comments and messages across platforms in one place.

UK-based support is worth mentioning too. Sendible is a London-based company, which means their support hours align well with European and UK time zones — something that can matter when you need help during your working day.

Auto media optimisation

One area where PostOnce has a clear edge is media handling. When you upload a video or image to PostOnce, it's automatically optimised for each platform at publish time. Instagram gets its ideal dimensions, YouTube gets the right format, TikTok gets vertical — all without you touching a thing.

Sendible doesn't offer this. You'll need to resize and reformat your media manually, or use a separate tool like Canva before uploading. If you're publishing the same content across 5+ platforms, that manual step adds up to a significant amount of time each week.

Recurring posts and content recycling

PostOnce has built-in recurring posts. Pick your days and time, choose which accounts to post to, and your evergreen content goes out automatically on schedule. It's straightforward and works well for content that stays relevant over time.

Sendible offers smart queues, which serve a similar purpose but with a different approach. You create content queues and Sendible cycles through them. It's a capable system, though arguably more complex to set up than PostOnce's simpler recurring model.

Who's Sendible better for?

If you're an agency managing social media for multiple clients, Sendible is genuinely worth considering. The client dashboards, white-label reporting, and approval workflows are built specifically for that use case, and they're well executed.

Sendible also makes sense if you need CRM integrations or a unified social inbox for managing comments and messages across platforms. These are features that matter for agencies and larger marketing teams, and PostOnce doesn't offer them.

Who's PostOnce better for?

If you're a solo creator, freelancer, or small business managing your own social accounts, PostOnce is the better fit. You get the scheduling and publishing features you need without paying for agency infrastructure you'll never use.

The flat-rate pricing means you're not penalised for being on more platforms. The auto media optimisation saves you genuine time every week. And the recurring posts feature handles evergreen content without the complexity of queue management.

At €12 per month versus $29 per month (for fewer accounts), the value difference is hard to ignore.
