Call leads without leaving the platform
Sendbox ships with VoIP calling, so leads get called from right inside the platform. Buy a phone number, load up calling credits, and start dialing. Calls record with playback, each caller earns a health score, and you see the lead's full context before you ever pick up the phone.

Dial without switching apps
Buy phone numbers and top up credits on the side. Make outgoing calls, take incoming ones, and leave voicemails without leaving Sendbox.
Phone numbers refresh on a monthly cycle to keep your caller ID looking clean and reduce spam flags.
See how likely your caller ID is to show up correctly on the recipient's phone, tracked as a display score.
Every call gets recorded, ready for playback whenever you need it for coaching, reference, or compliance.
Each caller carries a 0-to-100% health score, so you catch effectiveness issues early.
Name, company, LinkedIn, and location are all there before the call connects — you walk in prepared.
One click to call, logged automatically
Grab a local or toll-free number right inside Sendbox — provisioning is instant.
Credits get topped up separately from your plan and are consumed per minute across outgoing calls, incoming calls, and voicemail.
See the lead's name, company, LinkedIn, and location before you pick up. Click to dial straight from Sendbox.
Calls record with playback, and every caller earns a health score between 0 and 100% that tracks performance over time.
A lead's opened your email three times — they're paying attention. Call them from Sendbox with their full profile and email history right on screen.
Pair email sequences with phone follow-ups. Everything lives in one tool, so nothing gets lost between platforms.
Health scores per caller (0 to 100%) surface who's converting calls well and who could use coaching.
Calling that's native, not bolted on
A dialer that was part of the plan, not an afterthought
Smartlead only recently bolted on a dialer. Sendbox had calling from the start — recording, playback, caller health scores, and full lead context on every call. No add-on pricing, no third-party plugin to wire up.
You know the lead before you dial
Name, company, LinkedIn profile, and location are all visible before you place the call. Recordings with playback let you revisit conversations later, and per-caller health scores (0 to 100%) track effectiveness over time.
Got questions? We've got answers.
It's VoIP calling built directly into Sendbox. Buy a number, top up calling credits separately, and start dialing — outgoing, incoming, and voicemail, all from one tool.
