The InboxAlly + Klaviyo integration enables automatic seed synchronization, real-time contact validation, and advanced deliverability monitoring directly within your Klaviyo account.
Once connected, InboxAlly can: - Automatically sync InboxAlly seed emails into Klaviyo as profiles - Validate new subscribers in real-time via webhooks - Perform optional seed reenrollment for fresh engagement data - Provide detailed metrics on sync and validation activity
Prerequisites
Before you begin:
- Active InboxAlly account with an active subscription
- Admin access in your Klaviyo account
- Ability to authorize third-party apps in Klaviyo
For more integration options, see the Integrations Guide.
Step 1: Connect and Authorize Klaviyo
- Log in to your InboxAlly account.
- Go to My Account → Integrations → Klaviyo.
- Click Connect Klaviyo.
- You'll be redirected to Klaviyo for authorization.
- Review the requested permissions and click Allow.
After authorization, you'll see a success page and be automatically redirected back to InboxAlly. The integration will begin syncing your seed contacts within minutes.
Permissions Requested
InboxAlly requests the following Klaviyo permissions: - Profiles: Read and write profile data for seed management - Lists: Create and manage seed contact lists - Webhooks: Receive real-time subscriber events - Events: Track engagement and deliverability data
Step 2: Review Integration Status
Once connected, you'll see your Klaviyo integration dashboard with real-time metrics:
| Metric | Description |
|---|---|
| Integration Status | Shows if the integration is healthy and working |
| OAuth Token | Displays token validity and expiration date |
| Webhook Status | Shows webhook activity and last event received |
| Seeds Synced | Number of InboxAlly seeds currently in Klaviyo |
| Contacts Processed | Weekly count of contacts validated or synced |
| Validation Rate | Success rate for email validations |
Step 3: Configure Integration Settings
Sync IA Seeds
Toggle Yes to automatically sync InboxAlly seed addresses to Klaviyo. Seeds are synced every 10 minutes to keep your lists current.
Max Seeds to Sync
Set the maximum number of seeds to sync to Klaviyo. Default: 100 Increase this to match your testing volume needs.
Validate New Contacts
Enable this toggle to automatically validate new Klaviyo subscribers via webhooks. When someone subscribes, InboxAlly validates their email in real-time. This uses your InboxAlly validation credits.
Enable Seed Reenrollment
Enterprise feature that creates fresh engagement data for more accurate deliverability testing.
Reenrollment Cycle (Days)
Set how many days it takes to cycle through all seed profiles. Example: 10 days means ~10% of seeds are refreshed each day. Lower values = faster refresh, higher API usage.
Validation Rules
Configure which validation statuses are considered "valid." Options include: OK only, OK + Accept-All, or custom rules.
Step 4: Understanding Seed Management
How Seeds Are Synced
InboxAlly maintains your seed contacts in Klaviyo with special properties:
| Property | Description |
|---|---|
ia_managed |
"yes" for active seeds, "no" for removed |
ia_managed_type |
Seed type (standard, placement_tester, auditor) |
ia_validation_status |
Current validation status (valid/invalid) |
ia_validation_details |
Detailed validation result (ok, invalid, etc.) |
ia_mailbox_provider |
Email provider (Gmail, Outlook, etc.) |
ia_last_sync |
Timestamp of last sync |
What Happens to Removed Seeds
When seeds are removed from your InboxAlly allocation: - The Klaviyo profile is NOT deleted - Properties are updated to mark it as inactive - Historical engagement data is preserved - The profile can be reactivated if needed
Step 5: Monitoring & Logs
The integration dashboard provides detailed insights:
Weekly Metrics
- Contacts Processed: Total sync and validation operations
- Seeds Added: New seed profiles created this week
- Validation Success Rate: Percentage of successful validations
Sync Performance
- Last Sync Time: When seeds were last synchronized
- Sync Duration: How long the sync took
- Jobs Completed: Number of sync jobs this week
Performance Insights
InboxAlly provides actionable insights based on your metrics: - Sync performance recommendations - Validation rate alerts - Credit usage warnings
Step 6: Troubleshooting
| Issue | Cause | Solution |
|---|---|---|
| Token expired | OAuth authorization older than 6 months | Click Reconnect on the Klaviyo integration page |
| Webhook inactive | Webhook subscription failed or disabled | Click Setup Webhook to recreate the webhook |
| Seeds not syncing | Sync disabled or max seeds reached | Enable "Sync IA Seeds" and check "Max Seeds" setting |
| Validation not working | No available credits or feature disabled | Add credits and enable "Validate New Contacts" |
| Low validation rate | Poor quality contacts subscribing | Review your signup sources and list hygiene |
| Slow sync performance | Large seed count or API rate limits | Normal behavior—Klaviyo enforces rate limits |
Step 7: Disconnecting the Integration
To disconnect InboxAlly from Klaviyo:
- In InboxAlly, go to Integrations → Klaviyo.
- Click Disconnect Integration.
- Confirm the disconnection.
This will: - Remove all webhook subscriptions from Klaviyo - Clear OAuth tokens from InboxAlly - Stop all automatic syncing and validation
Note: Your seed profiles remain in Klaviyo but will be marked as no longer managed by InboxAlly.
Frequently Asked Questions (FAQ)
Q: How often does InboxAlly sync seeds with Klaviyo? A: Seeds are synced automatically every 10 minutes to keep your lists current.
Q: Does this affect my existing Klaviyo profiles? A: No, InboxAlly only manages profiles it creates. Your existing contacts are untouched.
Q: What happens when I run out of validation credits? A: Validation pauses automatically. Seed syncing continues (it doesn't use credits). Refill credits to resume validation.
Q: Can I control which seeds are synced to Klaviyo? A: Yes, use the "Max Seeds to Sync" setting to limit the number. Seeds are selected based on your InboxAlly allocation.
Q: Will synced seeds appear in my Klaviyo segments and flows?
A: Yes, seed profiles are regular Klaviyo profiles. You can filter them using the ia_managed property to include or exclude them from campaigns.
Q: How do I know if the integration is working? A: Check the integration dashboard for: - Green "Healthy" status indicator - Recent "Last Sync" timestamp - Active webhook status - Non-zero "Seeds Synced" count
Best Practices
- Start with default settings — The defaults work well for most users
- Monitor your first week — Check metrics daily to ensure everything is working
- Adjust max seeds as needed — Match this to your typical campaign volume
- Keep credits available — Validation pauses without credits
