Goals from Loops - Measure whether a campaign drove the desired outcome

How does Loops handle the deliverability side of things compared to something like Postmark, especially for transactional sends that need to land fast?

Quick question do you support a holdout or control group, so you can tell the email actually caused the conversion vs. it would've happened anyway?

@frantzlight Chris, opens and clicks have always felt like comfort numbers to me, so getting a straight answer on whether a campaign actually moved people is genuinely refreshing to see.

I really like the slideshow-style website.

The "opens and clicks are useful but they do not tell you whether a campaign worked" line is the frustration that killed my last three attempts at treating email as a serious channel. Every dashboard was clean and every meeting was hollow, because open rates went up but nothing downstream moved.

I run cold outreach rather than lifecycle email, but the same problem applies at a different layer. Reply rate is my proxy for outcome, but "reply" and "reply that led to a customer" are different metrics, and I have no good way to close that loop without stitching CRM data manually. Would be curious whether Goals is scoped only to product-usage conversion states inside Loops, or if there's a path to attribute against external systems (Stripe, Airtable, custom webhooks) for teams whose "conversion" doesn't live inside their SaaS.

Also the attribution window as a first-class input is smart. Most tools treat it as "check 30 days" without letting you match it to your actual sales cycle. Marketing-attribution problems mostly come from mismatched windows, not missing data.

Congrats on the launch! How does the attribution logic handle user-level vs. account-level conversions if a different teammate completes the upgrade?
