Email Delivery & Klaviyo Setup

How Tryvo sends emails to your customers through Klaviyo, which events you can trigger flows on, and which variables you can use in your templates.

Tryvo does not send emails directly. Instead, Tryvo pushes events into your Klaviyo account, and Klaviyo runs the flows you've configured to deliver the email or SMS to your customer.

This guide is for the brand operator setting up Klaviyo for the first time. It covers:

Why Tryvo uses Klaviyo (and not its own mailer)
The three events Tryvo will push
How to connect Klaviyo and build a flow per event
Every variable you can use in your email templates

You only need a Klaviyo account with admin access. Any active plan works for getting started — the free tier is enough to test the integration end-to-end.

Why Klaviyo?

Klaviyo's published partner pattern is that integrations like Tryvo push events, and the merchant builds the flow that turns events into emails. We use this pattern on purpose because it keeps the parts of email marketing that you care about in your hands:

You own the templates. Design, copy, layout, language — all in Klaviyo's editor.
You own the audience. Tryvo can't see, change or message anyone outside the customers who triggered an event.
You own deliverability. Email is sent from your verified Klaviyo sender, against your established sender reputation — not from a shared Tryvo mailer.
One place for marketing. Flows, segments, A/B tests and analytics for Tryvo events live alongside the rest of your lifecycle email.

In short: Tryvo handles when something interesting happens, Klaviyo handles what the customer actually sees.

The three events

Tryvo will push one of three events into Klaviyo. Each event becomes a Klaviyo metric you can build a flow on.

Event (metric name)	When Tryvo pushes it
`submission_invited`	A verified Shopify buyer is invited to record a UGC video
`submission_approved`	The AI quality gate has approved their submitted video
`reward_delivered`	The reward (discount code or cash payout) has been issued

You decide which of these you want to act on. A common setup is:

submission_invited → the magic-link invitation email (this one is required to actually launch a campaign)
submission_approved → a short thank-you email letting the creator know their video was accepted
reward_delivered → an email containing their discount code or confirming the cash payout

Connecting Klaviyo

Open the Klaviyo integration

In the Tryvo dashboard go to Brand → Integrations → Klaviyo.

Click Connect Klaviyo

You'll be redirected to Klaviyo, asked to sign in (if you aren't already) and then to Allow the connection.

Tryvo only requests two scopes:

events:write — to push the three events into your account
profiles:write — to keep customer profiles (email + first/last name) in sync

Tryvo does not get access to your lists, segments, templates or campaigns.

Confirm the green badge

After approval Klaviyo sends you back to Tryvo. You should see a green Connected badge on the integration page. That's it — the connection is live.

Letting the metrics appear

A metric only shows up in Klaviyo after it has been seen at least once. To make all three metrics available before you start building flows, send a test push for each one from Tryvo:

Open any Campaign in the Tryvo dashboard
Go to the Email tab
Click Send test for each of the three events

These test pushes are marked with is_test: true so you can filter them out of your real flows (see below). After the third test you'll find all three metrics in Klaviyo under Analytics → Metrics.

Building a flow per event

Repeat this for each metric you want to send email on.

Create the flow

In Klaviyo go to Flows → Create Flow → Create from Scratch.

Set the trigger

Choose Metric as the trigger type and pick the Tryvo metric, e.g. submission_invited.

Filter out test events (recommended)

Add a trigger filter:

is_test is not true

This prevents test pushes from Tryvo from triggering real emails to customers.

Filter by language (optional)

If you run campaigns in multiple languages, add a second filter:

campaign_language equals de (or en, fr, etc.)

Then build one flow per language so each customer gets the email in the right one.

Add the email step

Click Add Action → Email and design your template using the variables below.

Turn the flow on

Switch the flow status from Draft to Live. That's it — the next matching event from Tryvo will trigger the email.

Until each flow is set to Live, Klaviyo will collect the events but won't send any email. If customers are getting invited in Tryvo but not receiving emails, this is the first thing to check.

Variables you can use in templates

Every event Tryvo pushes carries a set of event properties. You can drop any of them into a Klaviyo template using the standard {{ event.<name> }} syntax.

Always available

Variable	Example value	Notes
`{{ event.customer_first_name }}`	`Anna`	Use a default: `{{ event.customer_first_name\|default:"there" }}`
`{{ event.customer_last_name }}`	`Becker`
`{{ event.brand_name }}`	`Acme Coffee`	Your public brand name
`{{ event.brand_logo_url }}`	URL to a PNG/SVG	Drop into an `<img src="…">`
`{{ event.campaign_name }}`	`Spring launch — espresso`	Internal name of the campaign
`{{ event.campaign_callout }}`	`Show us how you brew it.`	AI-generated CTA line
`{{ event.campaign_description }}`	Free text	Editable per campaign in Tryvo
`{{ event.campaign_language }}`	`de`, `en`, `fr` …	ISO language code
`{{ event.product_title }}`	`Single-origin Ethiopia`
`{{ event.product_image_url }}`	URL to a product image
`{{ event.reward_summary }}`	`15% off your next order`	Human-readable reward
`{{ event.is_test }}`	`true` / (missing)	Only set on test pushes

Only on `reward_delivered`

Variable	Example value	Notes
`{{ event.reward_code }}`	`THANKS-AB12CD`	The actual discount code
`{{ event.reward_expires_at }}`	`2026-07-01`	ISO date, optional

Only on `submission_approved` / `reward_delivered`

Variable	Example value	Notes
`{{ event.submission_thumbnail_url }}`	URL to a still from the video	Nice to show "the video you sent us"

Variable names are stable. New ones may be added over time, but existing ones won't be renamed or removed without a deprecation notice — your templates won't silently break.

Troubleshooting

The metric isn't showing up in Klaviyo. Send a test push from a Tryvo campaign — the metric only appears in Klaviyo after the first event arrives.

The flow is live but no email is being sent. Check that your trigger filter on is_test is not true isn't accidentally filtering out real events too. Also make sure the customer has a valid, subscribed profile in Klaviyo.

The email is sent but variables are empty. Look at the Event detail view in Klaviyo for that specific event — every property Tryvo pushed is listed there. If a value is missing, it usually means the campaign doesn't have that field filled in yet (e.g. no description, no brand logo).

Customers are getting duplicate emails. In each flow, add a Smart Sending window (Klaviyo's setting) so the same customer isn't emailed for the same metric twice within a short period.
