Comparison
Boomerang is really a scheduling and reminders tool — send later, snooze, follow-up nudges — with open tracking bolted on to its paid tiers. If read receipts are the feature you actually want, Vidi is purpose-built for them: clear ticks for opens, $2.99/month launch pricing.
Boomerang’s heart is scheduling and reminders. Vidi’s heart is telling you when your email was read. That difference in focus is the whole comparison.
| Feature | Vidi | Boomerang |
|---|---|---|
| Main purpose | Read receipts | Scheduling & reminders |
| Open tracking | Core feature | Secondary, on paid tiers |
| Read status at a glance | WhatsApp-style ticks in your inbox | Tracking within the app |
| Honest handling of automated opens | Yes — machine opens labelled, not faked | Reports raw opens |
| Works on Outlook.com & Yahoo Mail | Yes | Gmail / Outlook focused |
| Starting price | $2.99/month (limited launch price) | Free tier; tracking on paid plans |
Boomerang is excellent at send-later and follow-up reminders. But if you added it mainly to see whether your emails get opened, you’re paying for a scheduling suite to use one side feature. Vidi is built around the receipt itself.
Vidi shows the familiar ticks in your inbox and only turns them green on a genuine human open, labelling machine pre-fetches honestly — see Apple Mail Privacy Protection and open tracking.
Track reads across Gmail, Outlook.com and Yahoo Mail from one install.
The prices below are Boomerang’s own, and they are worth seeing in full rather than summarised — the cheapest tier is rarely the one that does what you came for.
| Boomerang plan | Price |
|---|---|
| Basic | Free 10 message credits per month |
| Personal | $4.98/month billed annually Gmail only — not Google Workspace accounts |
| Pro | $14.98/month billed annually |
| Premium | $49.98/month billed annually |

If your real need is scheduling emails to send later and getting nudged to follow up, Boomerang is the better tool — tracking is a bonus there. If it’s the receipts you’re after, Vidi does just that, more cheaply. The 30-day money-back guarantee makes the choice easy to test.
Vidi turns every important email into a clear grey-tick / green-tick answer — across Gmail, Yahoo Mail and Outlook.
