What should an agency look for in a social media management tool?

How to read this page

A scheduling tool publishes through each network’s official API, so it inherits that network’s rules and its limits. They are the same for every tool that is allowed to post, which is why they make a fair checklist. Everything below is from the networks’ own pages, read on 10 October 2026. We don’t rank vendors, and the only tool named is Mellow Hub, in its own section.

1. The account each client needs

Before you promise a client anything, check what the account is. Instagram’s publishing API works for professional accounts, and an account connected to a Page that requires Page Publishing Authorization can’t be published to until that is completed (Meta for Developers). What Mellow Hub asks for each network:

2. How a client hands over access

A client doesn’t have to hand over a password: most of these networks have a role for it. Meta lets a business share a Page with a partner at full control or for specific tasks, and requires the sharer to have full control of its portfolio and two-factor authentication on (Meta). X’s Delegate gives roles without a password (X Help). LinkedIn grants Page admin roles (LinkedIn Help). YouTube has channel permissions, with one catch: its page says invited users can’t use YouTube APIs, so ask a tool how it connects a channel you manage but don’t own (YouTube Help). Managing multiple social media accounts sets these side by side.

3. Limits that belong to the account, the app or the creator

These are the figures that decide how many clients one tool can serve. They live in the networks’ documentation, and a tool can only be as generous as they are.

4. What TikTok requires when an agency posts

TikTok’s guidelines set three rules an agency should know. The first is about who may build the integration: an app must be meant for a wide audience, and TikTok lists a utility tool that uploads to the accounts you or your team manage as not acceptable. That reads as covering an agency’s own in-house connector for its clients’ accounts, so an agency is better served by an app built and audited for many creators.

The second is disclosure. An app has to let the creator mark a post as promoting their own brand, which TikTok labels “Promotional content”, or another brand, labelled “Paid partnership”. Branded content can’t be private. Posting a client’s sponsored content without the right label is a mistake a tool should make hard.

The third is consent. The guidelines say content may be sent to TikTok only after the user expressly consents to the upload, with a preview, and that the privacy setting has no default. They don’t spell out who the user is when an agency posts for a client, so ask how a tool handles it.

5. Seats, clients and approval

The networks give you roles on their side. They don’t give you a client portal, a team calendar or a rule that nothing goes out without sign-off: those are features of the tool, so ask for them by name:

• Can each team member and each client have their own login, with their own permissions?
• Is there an approval step before a post is sent, and who can approve it?
• Is every action recorded, with who did it and when?
• Does removing a person or a client’s connection take effect at once?

6. Where Mellow Hub fits, and where it doesn’t

Hub is built for one account owner who runs several brands. A profile keeps one brand’s channels, schedule, queue, history, agent keys and audit apart from the others. It is not a team product: the pricing page says team seats, client logins and approval roles are not included, and the approval guide says Review mode limits an agent’s authority without adding a client portal or team invitations. A profile per brand and an approval you run yourself are what it has.

What it does have for delegation is an agent key or an OAuth grant that carries the channels, the mode (Review or Autopilot), a daily limit and an expiry you chose. Every action taken with one is written to a journal you can read, and revoking it takes effect on the next request. A key can’t create another key or approve its own post.

So for an agency whose staff and clients each need a login, Hub is not the fit. For one person managing several brands, it publishes to every network it supports, checking each network’s rules before sending.

Hub is paid: plans start at $19 a month (Solo), after a 7-day trial with a card on file that costs nothing if you cancel before it ends, and a monthly plan's first month is 20% off. Publishing is unlimited on every plan, under a fair-use ceiling that stops automated floods (900 publications a month on Solo). One publication is one post on one account, so a post sent to five networks counts as five. There are no automatic overage charges.
