# Sending limits and safety

The **Sending & safety** tab controls *how* and *when* a campaign sends. These settings keep your outreach inside LinkedIn's and your mail provider's limits, and inside your working hours, so your accounts stay healthy.

## 1. Sending accounts

| Setting | Used for |
|---|---|
| **LinkedIn accounts** | Visits, likes, comments, connection requests, LinkedIn messages, voice notes and InMails |
| **Email accounts** | Email steps. Choose SMTP/IMAP mailboxes or Gmail/Outlook. |

A new campaign starts with one of your connected accounts already selected for each channel. Check them before you launch.

Each field opens a dropdown of your connected accounts, with a search box when you have more than five. You can pick **up to 10 accounts per channel**, and each account shows its status and how many prospects it holds. Use **Select all** or **Clear** in the dropdown, or the **x** on an account to remove it.

When you pick several accounts on a channel:

- The first one is marked **Main**. Previews and reports use the main account. Click **Make main** on another account to change it.
- Each prospect is given one account per channel and keeps it, so the connection request, the messages after it and the email thread all come from the same sender.
- Daily limits, the gap between actions and the launch spread apply to **each account**. The line under the field shows the total, for example *"3 accounts share this campaign: up to 120 LinkedIn actions a day combined (40 each)."*
- On a running campaign, changes apply to prospects who haven't been contacted yet.

If an account stops working, the people it hasn't contacted yet move to another account in the campaign. People it already contacted wait for it if it only needs reconnecting. If it was removed for good, they start the sequence again from another account. If no account on that channel can send, Prosyo pauses the campaign and tells you. See [Paused by Prosyo](https://prosyo.com/docs/campaigns/launch-pause-resume.md#paused-by-prosyo). Accounts that were removed, for example because a plan or seat ended, no longer show in the dropdown, so you can pick a new one straight away.

No email account yet? [Connect one](https://prosyo.com/docs/connect-accounts/smtp-imap.md). If your plan has no mailbox, the tab says **Email steps aren't on your plan** and links to Billing.

## 2. Daily limits

Pick a preset, then fine-tune the numbers.

| Preset | Connection requests / day | LinkedIn actions / day | Emails / day | Best for |
|---|---|---|---|---|
| **Cautious** | 10 | 20 | 25 | New or recently connected accounts |
| **Recommended** | 20 | 40 | 50 | Most workspaces |
| **High volume** | 25 | 60 | 100 | Established accounts with strong reply rates |

New campaigns start on **Recommended**.

| Limit | What it counts | Guidance | Maximum |
|---|---|---|---|
| **Connection requests / day** | LinkedIn invites | LinkedIn recommends staying under 25 | 50 |
| **LinkedIn actions / day** | Every LinkedIn step: visits, likes, comments, invites, messages, voice notes and InMails | 40 is a safe pace | 150 |
| **Emails / day** | Emails sent | Warm new mailboxes gradually. Start near 25. | 500 |

Click **Save limits** after changing limits, or **Discard** to undo.

How the limits are counted:

- **Per sending account, per day**, in the campaign's timezone. An account used by several campaigns counts everything it sent that day, across all of them.
- **Only campaign steps count.** Profiles Prosyo reads for Intent and research, searches, imports and Chrome extension captures don't use up these limits.
- When an account reaches a limit, its next step waits until the next sending day.

> **Tip:** Start **Cautious** for the first week on a new account, move to **Recommended** in week two, and only use **High volume** when acceptance and reply rates are healthy.

> **Note:** LinkedIn also has its own weekly invitation limit, commonly reported at roughly 100 to 200 a week depending on the account. At 20 requests a day on five sending days, one account sends up to 100 a week. See [LinkedIn limits explained](https://prosyo.com/docs/help/linkedin-limits-explained.md).

## 3. Delay between actions

Every action waits a **random gap** inside a range you choose before it goes out. A launch is spread over the day instead of sending to everyone at once.

- Set a **Minimum gap** and a **Maximum gap**, between **5 and 60 minutes**.
- The default is **5 to 15 minutes**.
- The gap applies **per sending account**, across all campaigns using that account.
- Prosyo shows the resulting pace, for example *"5-15 min between actions — roughly 6 actions an hour per account"*.

Click **Save delay** to keep the change, or **Discard** to undo.

## 4. When a lead replies

**Turn off remaining steps when they reply** is **on by default**. When a prospect replies on LinkedIn or email:

- that person's enrollment is marked **replied**,
- none of their later steps are sent,
- the conversation appears in **Inbox**.

Leave this on. A follow-up after someone has replied looks automated.

## 5. Cancel an invitation if not accepted

Turn on **Cancel an invitation if not accepted till** and set a number of **days (1 to 30)**. It starts at 7 when you turn it on.

If the prospect hasn't accepted by then, Prosyo:

- **withdraws** the pending LinkedIn invite,
- **skips** later LinkedIn messages for that person,
- **still sends** email steps, if they have an email.

Pending invites that pile up can hurt your account. **7 to 14 days** is a good setting.

## 6. Intent and research

These options decide how the campaign uses research lines like `{{research.icebreaker}}` and what it may say about Intent activity. **They all start off** for every campaign you create, Intent-led campaigns and playbooks included. (The campaigns Intent sets up for **Send** on its **Today** feed can quote public posts and recognise link clicks.) Switch on only the ones you want.

| Option | When it's on |
|---|---|
| **Wait for research before sending** | If a person's research is still being written when a step that uses research lines is due, the step waits instead of sending your fallback text. Set how many hours to wait (1 to 72, 24 by default). After that, the fallback is used. |
| **Recognise people who click your links** | Links to your own tracked website get a short code, so a visit after a click shows on that person in Intent. The **They clicked a link you sent** condition then sees those visits too. |
| **Mention their public post** | Messages can use `{{signal.quote}}`, `{{signal.need}}` and `{{signal.url}}` to quote what the person asked for in public, like "Saw your post about needing a Shopify developer". Website visits are never mentioned this way. |
| **Allow mentioning what they looked at** | `{{intent.topic}}` can name the page topic they looked at, such as pricing. Most people prefer not to be told they were seen. |

See [Variables and personalization](https://prosyo.com/docs/campaigns/variables-personalization.md#research--intent-variables).

## 7. Working hours

Choose:

- **Timezone.** It starts as the sending timezone you picked when you created the campaign, or UTC for a one-click campaign from the **Library** in **Settings → Templates**. Usually your prospects' timezone.
- **Start and end time**, for example 09:00 to 17:30. New campaigns start at 09:00 to 18:00.
- **Days of the week**, for example Monday to Friday (the default). Keep at least one day on; to stop sending completely, pause the campaign.

Nothing sends outside this window. Actions that are due wait until the window opens.

You can change working hours and the timezone on a running campaign without pausing it. When you save, people waiting to be contacted move into the new hours straight away:

- People the campaign hasn't started on yet are spread out again from now, as at launch.
- Everyone else keeps their time, unless it falls outside the new hours. Then it moves to the next opening.
- Delays between steps are never shortened, and a step is never sent twice.

> **Tip:** Messages that arrive during the prospect's working day get more replies. If your list spans timezones, split it into one campaign per region.

## 8. Danger zone

At the bottom of the tab, **Delete campaign** removes a campaign that isn't running. Deleting can't be undone. To keep the reports, archive the campaign instead.

## How a sending day works

1. The campaign is **Running**.
2. Each enrolled person moves through the sequence in order.
3. Actions go out inside **working hours**, under **daily limits**, with a **random gap** between them.
4. LinkedIn messages wait until the person accepts your invite.
5. Emails send only if the person has an email and an email account is selected.
6. A reply stops their remaining steps.
7. Unaccepted invites are withdrawn after the days you set.
8. If a sending account stops working, its uncontacted people move to another account in the campaign. If none is left on that channel, the campaign pauses and you get a notification.

You don't need to keep Prosyo open.
