The add-on, Alerts and Slack

The add-on is an optional extra you can put on top of any plan. It adds Hide Sold Out and alerts, and you can also buy it on its own.

What you get

• Hide sold-out products, covered in Hide Sold Out.

• Alerts by email and Slack, so Timesact tells you when something happens in your store.

Adding it

1. Open Billing & Account → Billing and scroll to Plans & pricing.
2. On your current plan's card, tick the Add-on for box (it shows the monthly price), then click Add add-on. To add it while changing plan, tick the box on the new plan's card and click that card's button.
3. Approve the charge in Shopify, as you would for any plan change.

To remove it later, untick the box on your current plan's card and click Remove add-on. For current prices, see the Timesact listing on the Shopify App Store.

Alerts

Alerts are messages to you and your team, not to your customers. They are how you hear about something without having to watch the app.

There are three things Timesact can alert you about:

How often they arrive

For Pre-order created and Back in stock subscriber created you choose how often:

• Instant, an alert as soon as it happens.
• Daily digest, one message a day with everything grouped together.
• Weekly digest, the same but once a week.

Variant sold out is sent as it happens.

Where they go

Each alert can go to email, to Slack, or both:

• Built-in email: Timesact sends it. Enter the addresses you want it to reach, separating several with commas or new lines.
• Slack: connect Slack, then choose the channel the alert should post to.

Each alert has its own Alerts button, top right of a report in Analytics:

• Pre-order created: Analytics → Pre-order → Sales.
• Back in stock subscriber created: Analytics → Notify Me, Back in Stock and Waitlist → Subscribers & email performance.
• Variant sold out: Analytics → Sold-out products → Overview (shown once Hide Sold Out is set up).

In the Alerts window, for each frequency turn on Enabled, then tick Built-in email and enter the recipients, tick Slack and pick a channel, or both. Click Save.

Two different kinds of Slack message

The app has two Slack connections and they do different jobs, so it is worth knowing which one you are looking at:

• These alerts, about pre-orders, back-in-stock sign-ups and sold-out variants. They come with the add-on, and you set them up from the Alerts button on the matching Analytics report.
• Subscription alerts, which tell you about your plan usage and limits. You connect those under Billing & Account, on the Integrations tab, on the Slack card under Subscription alerts. They are not part of the add-on and they say nothing about your orders.

Plan usage alerts email you when your orders reach 50%, 70% and 100% of your plan's monthly limit. Change the email address in Billing & Account → Store settings, and connect Slack in Billing & Account → Integrations to get the same alerts in a channel. You can also set them up from the Plan usage alerts step on the home page.

The same Integrations tab also holds the Klaviyo connection, which is a third, separate thing again, covered in Notifications - Klaviyo.
