# Troubleshooting

> The CRM sync questions we get asked most, covering missing emails in Attio, contacts that never arrive and engagement fields that do not appear, and what to do about each.

## My sent emails do not appear in Attio's Emails tab

**This is expected, and there is a good fix.**

Attio's Emails tab is filled exclusively by Attio's own mailbox sync, mirroring inboxes you have connected to Attio directly. It is not open to other tools, so Fuse cannot write into it, and neither can any other platform.

Fuse records your sent emails as **notes** on the person instead. They are all there, just under Notes rather than Emails.

<Tip>
  Fuse sends campaign emails through **your own mailbox**, so those emails are already sitting in your Sent folder. Connect that mailbox to Attio's email sync and they will appear in the Emails tab natively, fully threaded, at no extra cost.

  In Attio, go to **Settings → Email & calendar** and connect the mailbox you send from. Attio supports Gmail and Outlook here.
</Tip>

## Nothing at all is syncing to my CRM

Check **Push contact records** first, under **Settings → Integrations → *your CRM*** on the **Sync** tab.

It is off by default and everything else depends on it. Emails and engagement attach to contact records, so with contact pushing off there is nothing to attach to and both are skipped rather than queued.

## Some people are not being added

Fuse only pushes people it has an **email address or phone number** for. Someone with neither is skipped by design. See [contacts and companies](/crm/contacts-and-companies).

Enrich them and they will be picked up on the next sync.

## Engagement fields are not appearing

Work through these in order:

<Steps>
  <Step title="Which CRM are you on?">
    Engagement fields are available on Attio today. HubSpot, Zoho and Pipedrive are in progress, and Salesforce is behind them. See [engagement on contacts](/crm/engagement).
  </Step>

  <Step title="Is Push contact records on?">
    Engagement is written onto contact records, so it needs contacts to exist first.
  </Step>

  <Step title="Has anyone actually engaged?">
    Fields only appear on people who have opened, clicked, replied or bounced.
  </Step>

  <Step title="Give it an hour">
    Sync runs hourly, not instantly.
  </Step>
</Steps>

## I edited a contact and Fuse overwrote it

It should not. When updating an existing record Fuse only fills fields that are **empty**, so your team's corrections stand.

The exception is a **manual push**, where you have explicitly asked Fuse to refresh the record. There, overwriting is the intent.

If you would rather Fuse never touched a particular field, turn it off on the **Fields** tab under **Settings → Integrations → *your CRM***. It will be left alone entirely from then on.

## Something synced late, or not at all

Fuse syncs on a schedule rather than instantly, roughly hourly for contacts, activity and engagement. Something that happened moments ago usually shows up within the hour.

Two things take longer:

* **First sync after connecting.** Fuse backfills your history in batches, which can take several passes on a busy account.
* **Dialer calls.** Fuse waits fifteen minutes after a call ends so the recording, outcome and transcript are attached, then picks it up on the next hourly run.

## Opens look far too high

Open tracking relies on a tracking pixel, and some email clients, Gmail most notably, load that pixel automatically before anyone has read the message. Opens are inflated as a result, across every tool that measures them this way.

Treat **Clicked** and **Replied** as the reliable signals of genuine interest.

## Still stuck?

[Get in touch](mailto:support@fuseai.com) and include the CRM you are using and the name of a contact that is not syncing as expected. That is usually enough for us to pinpoint it quickly.
