“Never takes a day off” isn’t a claim that your list cleans itself in the background — it’s about what’s available whenever you decide to run it. Zuhal runs on a 99.9% uptime SLA, so whether you check a list at 9am on a Monday or 11pm on a Sunday, the service is there. What actually cleans your list is still something you trigger: connect a platform, choose a list, verify. No exports, no waiting on a scheduled job.
Connect Your Platform
If your contacts already live in an email marketing or CRM platform, you don’t need to export a CSV every time you want to check a list. Zuhal connects directly to nine platforms via OAuth or an API key, depending on the platform: Mailchimp, HubSpot, ActiveCampaign, SparkPost, MailerLite, Moosend, Constant Contact, VerticalResponse, and iContact. Connect your account once from the Integrations page.
Choose a List
Once connected, pick the specific list, audience, or segment you want to check. You don’t have to verify your entire contact base every time — check a newly imported list, a segment you’re about to send a campaign to, or your full audience on whatever schedule makes sense for you.
Verify
Imported contacts run through the same verification engine as a CSV upload — 99.5%+ accuracy across syntax, domain, and mailbox-level checks, sorted into six result categories: Valid, Invalid, Catch-all, Disposable, Risky, and Unknown. See what each category means and how to act on it.
How Often Should You Clean Your List?
There’s no universal schedule — it depends on how fast your list grows and how much you send. As a starting point: verify new signups continuously (or at minimum before every campaign), and re-verify your existing list every one to three months, more often if you send frequently or your bounce rate has been creeping up. The point of an on-demand connection is that you can run a check whenever it makes sense, rather than being limited to whatever your CSV export workflow allows.
Why This Beats a Manual CSV Export
- No export step. Connecting once removes the recurring task of downloading and re-uploading a CSV every time you want to check a list.
- Always current. You’re verifying against your platform’s live list, not a snapshot that might already be a few weeks out of date by the time you get around to uploading it.
- Same accuracy either way. Integration-sourced imports and CSV uploads run through the identical verification engine — connecting doesn’t trade accuracy for convenience.
Don’t see your platform on the list? You can still verify any list via CSV upload, or use the REST API for real-time or bulk verification from anywhere. For the export steps if you’re going that route, see converting a list to CSV or TXT.
