Outreach & Deliverability
My prospects all have email addresses — why are some not getting emails?
My prospects all have email addresses — why are some not getting emails?
CallSine re-validates every email address before sending. If an address fails validation, the Agent will not send email outreach to protect deliverability and sender reputation. Even if you uploaded the email yourself, it must pass validation before outreach begins.
Can I keep sending InMails or Connection Requests while the Agent is using my LinkedIn account?
Can I keep sending InMails or Connection Requests while the Agent is using my LinkedIn account?
We discourage it. The Agent can’t see activity you perform directly on LinkedIn. Manual outreach can push you over LinkedIn’s daily, weekly, or monthly limits, which increases the risk of restriction.
Why didn’t my Agent send LinkedIn outreach to a prospect who has a LinkedIn account?
Why didn’t my Agent send LinkedIn outreach to a prospect who has a LinkedIn account?
The Agent checks LinkedIn eligibility before sending. For example:
Connection Requests: The prospect must be active on LinkedIn, which the Agent determines through multiple signals.
InMails: The prospect must have an Open Profile or be a 1st-degree connection.
Can I prioritize email over LinkedIn (or vice versa) for certain prospects?
Can I prioritize email over LinkedIn (or vice versa) for certain prospects?
No. The Agent uses performance-based optimization to determine the best channel for each prospect. It may switch channels based on response rates, sending limits, and deliverability.
Monitoring Agent Activity
Why does the Agent run every hour?
Why does the Agent run every hour?
The Agent operates in hourly cycles so it can continuously process new tasks, integrate changes, and manage responses without exceeding sending limits.
Why does the Agent work one day at a time?
Why does the Agent work one day at a time?
Daily batching allows the system to apply new optimizations and any edits you make before future actions are sent.
Agent Optimization
Why is my Agent not following the cadence on the Strategy page?
Why is my Agent not following the cadence on the Strategy page?
The cadence is a baseline. The Agent adjusts timing and channel order to test what works best and improve engagement.
Can I lock the Agent to a strict cadence?
Can I lock the Agent to a strict cadence?
No. A fixed cadence reduces performance. The Agent continuously tests timing, channels, and messaging to maximize results.
How long does optimization take?
How long does optimization take?
Optimization begins on day one, and improvements become more visible after 2–3 weeks of consistent sending.
Can my Agents share optimizations with each other?
Can my Agents share optimizations with each other?
Yes. Agent Networking allows Agents to share learnings and improvements across your account.
Note: Agent Networking is only available on the Enterprise plan.
Prospect Sourcing
Will multiple Agents send outreach to the same prospect?
Will multiple Agents send outreach to the same prospect?
No. The system is designed to ensure only one Agent is assigned to a contact at a time.
How does the Agent decide which prospects to bring in each day?
How does the Agent decide which prospects to bring in each day?
The Agent:
Pulls prospects matching your target persona and daily volume
Verifies contact data and email deliverability
Checks eligibility for your selected channels
If prospects fail validation, new ones are automatically added on the next hourly cycle.
What happens if my Agent runs out of prospects?
What happens if my Agent runs out of prospects?
Auto-sourced Agents: The Agent continues sending follow-ups and keeps searching for new prospects. The CallSine database refreshes regularly, so new leads become available over time.
Writing Outreach & Guardrails
How does the Agent decide what to write for each prospect?
How does the Agent decide what to write for each prospect?
The Agent uses your Materials, Style Guide, and campaign Guidance, combined with real-time research. Messaging is tailored to the prospect’s role, company, and industry.
Does the Agent reuse the same message for multiple prospects?
Does the Agent reuse the same message for multiple prospects?
No. Each message is unique to the prospect. The Agent may reuse successful structures, but not full messages.
Does the Agent ever stop itself from sending outreach?
Does the Agent ever stop itself from sending outreach?
Yes. Each day, the Agent runs a quality check on the previous day’s messages. If a message doesn’t meet internal quality or deliverability standards, the Agent will regenerate it before sending.
How does the Agent ensure messages meet deliverability best practices?
How does the Agent ensure messages meet deliverability best practices?
The Agent:
Validates contact data and avoids high-risk sending
Rotates sending accounts
Follows platform-specific limits
Avoids spam-triggering language
Performs daily quality checks
