How do I improve deliverability?

Verify your own sending domain in Settings → Communications → Email settings. A verified domain is required before you can send at all, and it also improves deliverability.

Where do unsubscribe categories come from?

From the email campaign categories set in Settings. They populate the categories recipients see on the email preferences page and classify your sends.

What do email tags do?

They're internal labels (set in email tag settings) for classifying and segmenting campaigns. They aren't shown to recipients.

How do I include one-to-one emails in the list?

Remove the Owner Type — exclude — Person filter on the Emails screen.

What can I A/B test, and how is the winner chosen?

Test subject lines, designs or calls to action. Set a split %, pick open rate or click rate as the success metric, and set a test duration; the winner then sends to the rest automatically.

Can I send from a contact's stakeholder leader?

Yes — switch on Stakeholder beside the sender name and/or sender email in the campaign's Recipients step, and set a fallback sender for contacts without one.

How do replies work?

By default replies go to the sender. Set a different Reply-To if you need replies to go elsewhere.

Do I need an Add/Update Contact block when sending a survey form?

No. Use the Survey block — email tracking ties the form submission to the recipient automatically.

How do I preview merge fields per contact?

Use Preview in the builder and select a contact to resolve the fields.

What does SwiftPredict do?

Where SwiftPredict is enabled for your account, it picks the best send time for each contact within 24 hours of the scheduled (or current) time, based on past behaviour (requires 5 or more prior opens). Contacts below that threshold are sent to as soon as the campaign begins sending.

How can I see who clicked which link?

Open the sent campaign → under Email status, the Link activity tab shows each link's Unique clicks → click a link to open Clicked by, the list of contacts who clicked it.

Why does my click rate look lower than before?

Click rate is now unique clicks ÷ delivered emails — the definition other email platforms use — instead of unique clicks ÷ opens, and past campaigns are recalculated the same way. Your results haven't dropped. The old figure is still available as Click-to-open rate: click the Clicked tile on the campaign's overview to see both.

Can I clone an existing campaign?

Yes — open the row menu (⋮) on a campaign and select Clone to copy its details and design into a new campaign.
