Postkey vs Blotato
Postkey vs Blotato
Postkey is the most agentic DM automation tool. Both automate Instagram and Facebook DMs, have an inbox, schedule posts and have an MCP server that can run all of it. Blotato is built around making and publishing content. Postkey is built around the DM: multi-step flows, sequences, AI replies, and your yes before an assistant sends.
The short answer
Postkey is the most agentic DM automation tool: one MCP connection lets your AI assistant build and switch on DM automations, answer the inbox, and schedule posts to 10 networks, across every account on your plan. Blotato is a content creation and publishing tool for 9 networks, with Instagram and Facebook DM automation and an MCP server of 35 tools. By its own docs, an assistant can build, edit and switch on its automations and schedule posts. Its automation sends one message with optional gates; Postkey adds the Flow Builder, sequences and AI replies, and an assistant's sends wait for your yes.

Why Postkey is the most agentic DM automation tool
Postkey's MCP server can build, edit and switch on automations. An agent can do the whole job:
- Build, edit and switch on DM automations: comment to DM, keyword DMs, follow to unlock, collecting emails.
- Read the inbox, draft replies and send them once you say yes.
- Write, schedule and publish posts, and set the DM keyword each post's comments reply to.
- Find and tag contacts, and report how posts and automations did.
- Up to 52 tools in one MCP server, with OAuth sign-in or an agent key, and a skill file that teaches the agent the rules.
- Approvals, limits and protection from instructions hidden in DMs built in, so you can let an agent run it.

| Blotato | Postkey | |
|---|---|---|
| Comment to DM and keyword DMs | Yes | Yes |
| Follow to unlock | Yes (Instagram only) | Yes |
| Collect emails in the DM | Yes (an email gate) | Yes |
| Shared inbox | Yes (one inbox for Instagram and Facebook Pages) | Yes |
| AI replies | Not listed | From Create |
| DM channels | Instagram and Facebook Pages | Instagram and Messenger |
| Post scheduler | X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky and Pinterest | Instagram, TikTok, Facebook, Telegram, LinkedIn, YouTube, Threads, Pinterest, Bluesky and Google Business |
| Instagram accounts | "Max connected social accounts: 20 on Starter, 40 on Creator, 100 on Agency. Each Facebook Page and LinkedIn company Page counts as one." | Up to 15 on one plan, sharing one contact allowance |
| How usage is billed | Active contacts a month, counted per connected account; past the limit, DMs to new people fail until the monthly reset or an upgrade. | Plans include contacts each month, shared by all the plan's accounts; extra contacts are charged, never cut off |
Blotato has no free plan: a 7-day trial on every plan, card required, without the API or MCP server. Yearly billing is about 17% off ("pay for 10 months and get 12").

How far one DM automation goes
Both have comment to DM, keyword DMs, a follow gate and an email gate. The difference is how much one automation can do, and how much an assistant may do without you.
| Blotato | Postkey | |
|---|---|---|
| What one automation sends | One message, with an optional follow gate, email gate, public reply and webhook, always in that order | A flow from the Flow Builder canvas, with steps and branches, or one message from the Quick Automation editor |
| Triggers | A comment, a DM, or both | Comments, keyword DMs, story replies, story mentions and Live comments |
| Story replies | Not a trigger of their own: "A reply to your story arrives as a normal DM and fires a message trigger." | A trigger of their own |
| Sequences of follow-up messages | Not listed | Yes |
| AI replies | Not listed: the automation sends the message you wrote | From Create |
| An assistant edits a live automation | "Content changes to a live automation publish immediately." | Saved to a draft; people keep getting the live version until it is switched on again |
| An assistant switches on an automation or sends a DM | Blotato's docs tell the assistant to ask you first; the tool acts when it is called | It waits in Approvals for your yes, by default |
| What an assistant can build | Every part of a Blotato automation | Automations from Postkey's templates; a Flow Builder automation is changed in the Flow Builder |

Where Blotato is a good fit
- Content creation in the same tool: unlimited AI writing, plus images, carousels, infographics and videos made with AI from templates, and ElevenLabs voiceovers.
- Far more connected accounts per plan: 20 on Starter, 40 on Creator, 100 on Agency.
- Publishes to 9 networks from one call, X among them.
- A 35-tool MCP server in the official MCP Registry, a REST API on every paid plan, and official n8n and Make nodes.
- DM automation with a follow gate, an email gate, a public reply and a webhook, all of which an assistant can set over MCP.
Where Postkey is the better fit
- You want more than one message per automation: branches in the Flow Builder, and sequences that follow up later.
- You want AI replies in your DMs (from Create).
- You want triggers beyond a comment or a DM: story mentions and Live comments.
- You want an assistant's edits, switch-ons and sends to wait for your yes, enforced by Postkey rather than left to the assistant.
- You post to Telegram and Google Business, which Blotato does not list.
- You want to keep answering new people when a busy month passes your contact allowance: Postkey charges for the extra contacts instead of stopping.
Switching from Blotato
- 01
Connect your Instagram account to Postkey with Meta's sign-in.
- 02
Ask your assistant to rebuild your keywords and links as Postkey automations, or paste them in yourself.
- 03
Check the DM on the phone preview, then switch it on. Turn the Blotato version off so people do not get two DMs.
