OnyxSend vs Reply.io

OnyxSend is a managed service that handles prospect research, personalized outreach writing, and deliverability for you, so your team shows up to close booked meetings instead of running sequences.

Pick OnyxSend if
- You want researched prospects and written sequences delivered to you, not a tool you have to staff, configure, and manage yourself.
- Your team's time is better spent on discovery calls and closing than building sequences, sourcing lists, and debugging deliverability.
- You need a predictable number of qualified meetings per month and want a service accountable to that outcome, not just seat licenses.
Pick Reply if
- You have in-house SDRs who want full hands-on control over sequence building, and prefer a self-serve platform at a lower entry price point.
- You need an AI auto-responder (Jason) to handle reply threads autonomously, run multi-client agency accounts, or require WhatsApp and SMS channels out of the box.
FAQs
Does OnyxSend include prospect research or do I supply my own list?
OnyxSend includes prospect research in every plan: 1,000 researched prospects per month on Growth, 3,000 on Pro, and 10,000 on Scale. You do not need to source, enrich, or clean a list. Reply.io has a built-in B2B database you can search yourself, but identifying, qualifying, and pulling the list is your team's responsibility.
Reply.io has Jason, an AI SDR. Does OnyxSend have something similar?
Not directly. Jason in Reply.io auto-responds to prospects mid-thread, which is useful if your sequences generate more replies than your team can handle manually. OnyxSend's service includes outreach writing and meeting-booking workflows on Pro and Scale, so qualified replies route to calendar booking rather than an AI auto-responder. If autonomous conversation handling is a core requirement, Reply.io has a clear advantage there.
Which platform handles deliverability better?
OnyxSend manages deliverability as part of the service, including sending infrastructure, warmup, and ongoing monitoring. Reply.io provides deliverability tooling, including inbox rotation and warmup integrations, that you configure and maintain yourself. If you would rather not own that layer, OnyxSend removes it from your plate entirely.
Can I run multi-channel sequences on OnyxSend?
Yes, on the Pro ($2,497/month) and Scale ($4,997/month) tiers, which include multi-channel orchestration. Growth ($997/month) focuses on email sequences. Reply.io supports multi-channel across its plans, including LinkedIn, calls, SMS, and WhatsApp, with self-serve control over every step.
Is OnyxSend right for a solo founder or small team?
Yes. The Growth plan at $997/month covers 1,000 researched prospects, five active sequences, and a weekly performance review. It is built for founders who want a pipeline running for them without hiring an SDR. Reply.io is also accessible at lower price points, but you are operating the tool yourself, which takes time and sales ops experience to do well.
Does Reply.io offer an agency plan? Does OnyxSend?
Reply.io has dedicated agency and white-label tiers, making it a reasonable choice if you are managing outreach on behalf of multiple clients. OnyxSend does not currently offer an agency or white-label plan, so if multi-client account management is a requirement, Reply.io is the better fit for that use case.
