Sending limits

Every connected email or LinkedIn inbox has its own daily and weekly sending caps. These exist to keep sending volume within what mailbox providers and LinkedIn consider normal for a human account, protecting deliverability and account health.

​

Default limits

If a LinkedIn account is on Sales Navigator, its defaults are raised, since Sales Navigator accounts tolerate more LinkedIn activity:

​

Can I change these limits?

Partly. The two daily message limits — emails per day for an email inbox, LinkedIn messages per day for a LinkedIn inbox — can be raised or lowered per inbox by asking Swan in chat. Each channel has a ceiling the limit can’t exceed: Connection-request limits (daily and weekly) are fixed defaults and can’t be changed. There’s no settings screen for limits — chat is the only place to set them. If you want to throttle an inbox below the caps without changing its limit, the other lever is the sending window, configured at Tools → Outreach → Configuration (where sending hours and days are set): Swan advances at most one email per inbox roughly every 3 minutes, so each hour of sending window allows roughly 20 emails per inbox. Restricting an inbox’s sequences to a one-hour window, for example, caps that inbox at roughly 20 emails a day regardless of the 150/day limit. See Scheduling and cadence for how the pacing works.

​

Resets

Daily counters reset at 00:00 UTC. The weekly connection-request counter resets every Sunday. Resets apply per inbox, not per sequence, so an inbox’s usage is shared across every sequence it’s assigned to.

​

What happens when a limit is hit

When an inbox hits a limit for a given channel, any contact whose next step needs that channel is parked in a “waiting on limits” state instead of erroring out. Once the counter resets (or a limit is raised), the contact becomes eligible for the next scheduling pass, provided the sending window and any other prerequisites are met. See Scheduling and cadence for how often that pass runs. A Pending LinkedIn message can also be waiting for connection acceptance. Resetting or raising the inbox’s limit does not clear that requirement. After acceptance, the message becomes eligible for sending; if the invitation remains unaccepted, the periodic invitation check closes the LinkedIn message path after about 2 weeks. See Replies and stop conditions for rejection and expiry outcomes.

​

One inbox per channel

A sequence sends through at most one inbox per channel: one email inbox for its email steps and one LinkedIn inbox for its connection requests and messages. The two can belong to different people, but you can’t assign several email inboxes to one sequence or vary the inbox per step. To spread volume across several email addresses, split the contacts into separate sequences, each with its own inbox; each sequence then draws on its own inbox’s daily and weekly caps.

Common questions

What’s the actual daily email limit per inbox? 150 emails per day by default, per inbox — you can lower it in chat, but not raise it above 150. Actual volume is limited by both the configured daily cap and pacing: a 10-hour window allows roughly 200 scheduling opportunities, but the inbox still sends at most 150 emails, or its lower configured limit. Do limits reset at midnight in my timezone? No — resets happen at 00:00 UTC for everyone, regardless of the sequence’s or inbox’s timezone. If a contact is “waiting on limits,” do I need to do anything? If the only blocker is the inbox’s limit, sending resumes automatically on an eligible scheduling pass after the counter resets or the limit is raised. A Pending LinkedIn message may instead be waiting for connection acceptance, which a limit reset won’t clear. See Replies and stop conditions for what happens if the invitation is never accepted. Does having Sales Navigator automatically raise my limits? Yes, Sales Navigator accounts get higher default LinkedIn limits than standard accounts. Can I use multiple inboxes to increase throughput? Not on the same channel within a single sequence — each sequence has at most one email inbox and one LinkedIn inbox. To scale volume, split your contact list into several sequences with a different inbox on each; total daily throughput then grows with the number of sequences/inboxes. Can I change the daily sending limit for an inbox? Yes for emails per day and LinkedIn messages per day — ask Swan in chat. Limits can’t exceed the channel ceiling above, and connection-request limits are fixed. Are limits shared across sequences, or does each sequence get its own quota? Limits belong to the inbox (connected account), not the sequence — an inbox used in five sequences still has one daily quota shared across all of them.
