Connect Any IMAP Mailbox to Perplexity

Updated 1 November 2026

Yes — Perplexity can read, search and reply to your Any IMAP Mailbox through Mailopoly. Connect Any IMAP Mailbox to Mailopoly with your mailbox password and the IMAP server address, add Mailopoly to Perplexity as a custom connector, sign in and ask. One connection covers IMAP mailbox and every other account you own. Mailopoly detects the server from your domain's mail records and fills it in; you can edit the host and port if your provider uses something unusual, and some providers require an app password instead of your normal one.

Connect Any IMAP Mailbox to Perplexity in three steps

1 Connect Any IMAP Mailbox to Mailopoly

Start a Mailopoly account at mailopoly.com/sign-up — 7-day free trial, no credit card.
In Mailopoly choose Add email account and enter your full address. Mailopoly looks up your domain's mail records and fills in the IMAP server and port.
Enter your mailbox password — the one you use for webmail — unless your provider requires an app password, in which case generate one in your provider's security settings.
If the connection fails, check the host and port against your provider's IMAP settings page (usually the same host you'd use in Apple Mail or Outlook, port 993 with SSL) and edit them in Mailopoly.

2 Add Mailopoly to Perplexity

This part is the same whatever you connected in step 1.

Add Mailopoly to Perplexity

These steps are taken from public documentation, and we haven't yet checked each one in Perplexity ourselves. If a label doesn't match what you see, Perplexity's own help page, linked below, has the current wording.

In Perplexity, open Account settings → Connectors.
Choose + Custom connector at the top right, then Remote.
Name it Mailopoly and enter https://fastapi.prod.aws.mailopoly.com/mcp-server/ as the MCP Server URL. For Authentication choose OAuth 2.0 — there's no client ID or secret to fill in, Mailopoly registers Perplexity itself — and for Transport choose Streamable HTTP.
Tick the box confirming you understand the risks of custom connectors, choose Add, then click the Mailopoly card to sign in.
Sign in with your Mailopoly account, then choose what Perplexity is allowed to do. Reading, making changes and sending are separate permissions.
Back in Perplexity, ask.

Perplexity takes Mailopoly as a custom remote connector, so the only thing to paste is one address. Custom connectors are available on Perplexity Pro, Max and Enterprise; on Enterprise, an admin has to allow them for the organisation first.

3 Ask about your IMAP mailbox

Whatever you've connected to Mailopoly is what your assistant can reach. Some things people ask on day one:

What's in the Cleanbox for my company domain today?
Find the hosting renewal invoice in my work mailbox and tell me the amount.
Reply to the client's last email from my company address.

Any IMAP Mailbox server settings

Mailopoly fills these in for you when you enter your address. They're here in case you need to check them or your provider uses something unusual.

IMAP server	Detected from your domain (editable)
Port	993
Security	SSL/TLS
Username	Your full email address
Password	Your mailbox password, or an app password if your provider requires one

What Perplexity can do with Any IMAP Mailbox through Mailopoly

Search Any IMAP Mailbox — and every other account you own — in one question. By sender, date, topic, or the half-remembered phrase somewhere in the body.
Read your Cleanbox, not your whole inbox. Mailopoly sorts IMAP mailbox as it arrives: personal and important mail in Cleanbox, promotions and newsletters in Other. Ask for either.
Summarise a thread, a day or a week. "What did the school send this week?" comes back as an answer, not a list of links.
Reply from your IMAP mailbox address, in your voice. Save a draft to Mailopoly for review, or send — sending is a separate permission and a confirm-first action.
Schedule a send for later, and cancel it if you change your mind.
Pull out invoices, events and deliveries. Amounts and due dates, calendar invitations, parcel tracking — extracted on arrival and added to My Day.
Find an attachment. Every attachment from IMAP mailbox lands in PolyBox, so "find the PDF the accountant sent" just works.
Unsubscribe, snooze, file and mark read from the chat, on whichever account the mail belongs to.

Reading, making changes and sending are separate permissions you grant when you connect, and you can revoke Perplexity at any time from Settings → Security in the Mailopoly app. More on the security page.

What goes wrong with Any IMAP Mailbox, and the fix

The username is usually your full address, not the part before the @. Some hosting providers use a separate mailbox username — it's shown in your hosting control panel.
Port 993 with SSL/TLS is what nearly every provider uses. If yours only offers STARTTLS on port 143, set that in Mailopoly's advanced settings.
Providers that need an app password rather than your normal one include Mail.ru, Orange, AT&T and any account with two-factor authentication turned on. Your provider's IMAP help page will say.
Proton Mail, Tutanota and Hey don't offer standard IMAP, so they can't be connected this way.
No + Custom connector button in Perplexity: custom connectors need Perplexity Pro, Max or Enterprise. On Enterprise, ask your admin to allow custom connectors for the organisation.
The Mailopoly card says it isn't connected: adding the connector doesn't sign you in. Click the Mailopoly card in Account settings → Connectors and finish the Mailopoly sign-in.
Perplexity can't reach the server: check the address is exactly https://fastapi.prod.aws.mailopoly.com/mcp-server/, Authentication is OAuth 2.0 and Transport is Streamable HTTP, then remove the connector and add it again.
