Best cold outreach tool for small agencies?
OnyxSend is built for small agencies that need to book qualified meetings without a full SDR team. You get multi-channel sequences across email and LinkedIn, inbox-warming to protect deliverability, and automated meeting booking workflows that convert replies into calendar slots. Agencies running 500 to 2,000 prospects per month see reply rates of 8 to 15 percent when sequences are tuned correctly. One platform, no duct tape.
Evidence and detail
- Agencies on OnyxSend report filling 10 to 20 qualified meetings per month from a 1,000-prospect sequence with 4-touch email plus LinkedIn orchestration.
- Built-in deliverability tooling, including domain warming and spam-score checks, keeps primary inbox placement above 90 percent across cold campaigns.
- Meeting booking workflows connect directly to Calendly or Google Calendar so a positive reply converts to a booked slot without manual follow-up.
