SendGrid integration — transactional email and inbound parse
Oneop sends transactional email through SendGrid and accepts SendGrid Inbound Parse, turning inbound support mail into tickets with two-way replies.
SendGrid is one of two transactional email providers Oneop supports (the other is Postmark). It carries the platform’s operational mail and, optionally, your inbound support mail.
What it does
Outbound transactional email. Notifications, invitations, survey links and other operational mail deliver through SendGrid.
Inbound email-to-ticket. Point SendGrid Inbound Parse at your Oneop deployment and inbound support mail becomes tickets. The ingest pipeline is the careful part: every message is deduplicated through a ledger keyed on workspace plus RFC822 Message-ID — shared across all three inbound pipelines (IMAP, Postmark, SendGrid), so the same email arriving twice by different routes still creates one ticket. Threading uses In-Reply-To/References headers with a [#TKT-nnn] subject backstop. Replies are two-way: an agent’s public reply emails back to the customer and their answer lands on the same ticket. Internal notes are never emailed.
What flows, in which direction
- Outbound: transactional email.
- Inbound: parsed email delivered to the email-to-ticket pipeline.
- Inbound webhook authentication is token-verified.
Setup
Outbound requires a SendGrid API key configured on the deployment. Inbound requires the email-to-ticket module enabled and an Inbound Parse route pointed at the platform.
What it does not do
- SendGrid is a delivery channel, not a marketing suite connection — no SendGrid marketing campaigns, lists or template sync.
- Delivery is only as configured: without a SendGrid key, Oneop does not claim guaranteed delivery through it.

Email-to-ticket is off until you ask for it — while it is off, the mailbox APIs return 404 and the poller does not run. See Help desk.
