Pick OnyxSend if
- You want researched, qualified prospects delivered every month without managing a data vendor, copywriter, or SDR tool yourself.
- Deliverability and reply rates are the bottleneck; you need someone accountable for inbox placement, not just a warm-up toggle.
- Your team is too small to run outreach operations in-house but too revenue-focused to let pipeline sit idle.
Pick Lemlist if
- You already have a prospect list and a research process; you need a flexible tool to build and A/B test sequences at low cost.
- Custom image or video personalization is central to your brand's outreach style and you want hands-on creative control.
FAQs
Is OnyxSend more expensive than Lemlist?
Yes, OnyxSend starts at $997/month versus Lemlist's ~$59/user/month entry point. The difference is what you're buying: Lemlist is software you operate yourself; OnyxSend researches your prospects, writes the copy, manages deliverability, and optimizes campaigns for you. For teams without a dedicated outreach function, the total cost of running Lemlist in-house, including your time, data subscriptions, and copywriting, often exceeds OnyxSend's retainer.
Does OnyxSend do LinkedIn outreach?
Yes. Multi-channel orchestration, including LinkedIn steps alongside email, is available on the Pro ($2,497/month) and Scale ($4,997/month) plans.
Does Lemlist book meetings for you?
No. Lemlist handles the sending and sequence steps, but converting replies to booked meetings is manual work on your end. OnyxSend includes meeting booking workflows on Pro and Scale plans.
How does OnyxSend handle deliverability compared to Lemlist's Lemwarm?
Lemwarm is an automated inbox warm-up tool you configure and monitor yourself. OnyxSend's deliverability management is fully handled: domain health, sending infrastructure, warm-up cadence, and bounce monitoring are all included in every plan, with no setup required from you.
Can I use both OnyxSend and Lemlist?
Technically yes, but there is little reason to. OnyxSend covers the full cycle from research through booked meeting. If you have an existing Lemlist setup for a specific segment and want OnyxSend for net-new prospecting, they can coexist, but you should audit whether the overlap is worth the cost.
What if I already have a prospect list? Do I still need OnyxSend?
If your list is clean, well-researched, and regularly refreshed, you may get more value from a DIY tool like Lemlist. OnyxSend's biggest advantage is the research layer: 1,000 to 10,000 freshly researched prospects per month with account context baked into the copy. Without that, you are paying for a managed service whose core output you are already supplying yourself.
