Analytics1 Score result
#1 cold email software with deliverability and analytics, by the Analytics1 Score: Apollo.io (87/100)
Scored from vendors’ own published pages with fixed weights; partner and sponsor status are not inputs. How the score works.
How to choose
- Data included or bring your own: a built-in database saves a tool, but check its accuracy in your market.
- Mailbox model: unlimited sending accounts and warm-up suit agencies and high volume.
- Deliverability tools: warm-up, inbox placement tests, sending limits per mailbox.
- Reply tracking over opens: open tracking pixels hurt deliverability and Apple Mail inflates opens. Measure replies, positive replies and meetings.
- Compliance: unsubscribe handling, suppression lists and data sources you can explain.
The ranking
Ranked by the Analytics1 Score, from evidence read on each vendor’s own site on 19 October 2026. Affiliate partners and sponsors are scored by the same rules as everyone else: being a partner or buying a placement has no effect on a score or a position. We have not tested these products in a live account.

The metrics that matter in cold email
| Metric | What it tells you |
|---|---|
| Bounce rate | List quality. Verify first with a tool such as Bouncer. |
| Reply rate | Whether the message and audience fit |
| Positive reply rate | Whether you reach the right people with the right offer |
| Meetings per 1,000 contacts | The number to compare campaigns and channels on |
| Spam complaints | Sender reputation risk; keep under Google's 0.3% threshold |
Comparisons: Instantly vs Lemlist, Amplemarket vs Apollo, Apollo vs ZoomInfo. Deliverability for newsletters and marketing email is covered in the best email marketing tools for analytics and deliverability.
Questions
- Should I track opens in cold email?
- Many senders turn open tracking off. The tracking pixel can hurt deliverability, and Apple Mail Privacy Protection marks many unread emails as opened. Replies and meetings booked are better measures.
