42's Recommendation by Team Size

| 10-50 reps |

The Real Differences (42's Practitioner POV)
"Outreach and Salesloft have been feature-matching each other for years."
The winner is whoever gives you the better deal. We've seen 40-60% discounts from both when there's competitive pressure. Play them against each other.
"Apollo's all-in-one approach eliminates integration headaches."
Data + sequences in one platform means no ZoomInfo sync issues, no contact ownership conflicts, no "who enriched what" debates. For lean teams, this matters more than fancy AI features.
"Deliverability is table stakes—all three are fine if you warm domains properly."
We see teams blame their SEP for deliverability issues when the real problem is domain hygiene. Warm your domains, rotate sending accounts, and all three platforms will work fine.
What We Actually Care About
+ What Matters
- +CRM sync reliability: Does it actually write back to Salesforce/HubSpot without dupes?
- +Email deliverability infrastructure: Throttling, warmup, domain health monitoring
- +Analytics that connect to revenue: Can you tie sequences to closed-won deals?
- +Rep adoption: Will your team actually use it? Complexity kills adoption.
- What's Overhyped
- -"AI writing": Gimmicks. Your best reps write better than any AI. Train humans.
- -"Intent data" in SEPs: Buy it separately (6sense, Bombora) if you need it.
- -"Conversation intelligence": Nice-to-have, not make-or-break for most teams.
- -"Advanced branching": 90% of sequences are linear. Don't overcomplicate.
