Pick the tolerance window
Step 1 of the cadence sends within a 4-hour tolerance window (e.g. 9am-1pm sender time). Step 2 and later within a 24-hour tolerance window.

Send-Time Batching
A sales-ops lead wants to apply send-time optimization to outbound cadences without rebuilding the sequence engine.
Send-time optimization lifts open and reply rates on prospects with prior engagement history. The structural challenge is applying it to outbound cadences (which typically send at fixed times) without breaking the cadence design.
Send-time batching is the workflow pattern that bridges the gap: cadences keep their fixed step structure but each step's actual send time is optimized per recipient within a tolerance window.
The problem this pattern solves
Outbound cadences send at fixed times (often 'Tuesday 10am sender time'). The fixed time is wrong for most recipients. Send-time optimization solves the per-recipient question but cadences can't fully change their send time without breaking pacing.
The pattern
2
Per-recipient optimal-hour prediction
Outsolvi's send-time model predicts each recipient's optimal hour within the tolerance window based on their engagement history.
3
Batched sends per hour
Within the window, recipients are batched by predicted optimal hour and sent at that hour.
4
Fallback for no-history prospects
Cold prospects with no history get the industry-cohort default within the window.
5
Measure lift
Compare open and reply rates pre and post send-time batching. Expected lift: 8-15 percent open, 5-10 percent reply on prospects with prior engagement.
How Outsolvi enables it
Outsolvi's send-time optimization model exposes per-recipient optimal-hour predictions via API. Cadence engines (Outsolvi cadence, Saleshandy, Outreach.io) can consume the predictions and batch accordingly within their tolerance windows.
Pattern variations by stage
Cold outbound
Cohort-default optimization only; per-recipient lift is small without prior engagement data.
Warm outbound
Full per-recipient optimization; prospects with 3+ prior engagements get individual hour predictions.
Renewal motion
Per-recipient optimization on customer engagement data; lifts in the 10-20 percent range on customer cohorts.
Frequently asked questions
Does this delay urgent sends?+
Send-time batching has a per-step opt-out. Urgent sends bypass the optimization and fire immediately.
Does this interact with deliverability throttling?+
Yes, positively. Batched per-recipient sends spread the send volume across a 4-24 hour window, which reduces the receiver-side rate-limit signal.
