Some things LinkedIn tells Kerux right away. Others Kerux has to go and check, and every check counts toward a daily limit for each LinkedIn account. Kerux keeps those checks low on purpose, so your account looks like a person using LinkedIn and your campaigns always have room to send. ## What arrives and when | What happens on LinkedIn | When Kerux sees it | | - | - | | Someone replies or writes to you | Right away | | You send a message (from Kerux or from LinkedIn itself) | Right away in conversations Kerux already has; a new conversation within 1 hour on weekday daytime, up to 2 hours on weekends and at night | | Someone accepts your invitation (new connection) | Usually within minutes; LinkedIn can take up to 6 hours | | Someone starts following you | Usually within minutes; LinkedIn can take up to 6 hours | | Someone sends you an invitation | Within about an hour in the daytime (inbox **Invitations** tab), or on the check schedule below | | Someone views your profile | On the check schedule below | | Reactions and comments on a post you watch (Signals) | A few times a day, during the day | Replies, messages, new connections and followers arrive at any hour, day or night. ## Check schedule Kerux checks for invitations you received and profile views on this schedule when a campaign starts from that event (**Invitation received** or **Profile view**, see [Triggers](/help/campaigns/automations.md)) on that account. Without such a campaign, invitations are still checked for the inbox's [Invitations tab](/help/inbox/linkedin-invitations.md): once an hour from 7 AM to 10 PM on weekdays (every 2 hours on Saturday and Sunday), once an hour from 10 PM to midnight, and once every 2 hours from midnight to 7 AM. One check serves both. It also reads your chats from time to time as a backup, in case LinkedIn missed telling it about a message. | Time in your LinkedIn account's time zone | Invitations received and profile views | Backup read of your chats | | - | - | - | | 7 AM to 10 PM, Monday to Friday | Every 15 minutes | Every hour | | 7 AM to 10 PM, Saturday and Sunday | Every 30 minutes | Every 2 hours | | 10 PM to midnight | Once an hour | Once an hour | | Midnight to 7 AM | Once every 2 hours | Once every 2 hours | On the campaign's start box and in its **Triggers** tab, an **Invitation received** or **Profile view** trigger shows when Kerux last checked and when it checks next (for example "Checked 3 minutes ago ยท next in 12 minutes"). To check sooner, open the campaign's **Triggers** tab and click **Check now** on the trigger (owners and admins): Kerux looks on LinkedIn right away and says how many people it found, how many are new and how many started the campaign. You can do it 3 times a day per trigger; the button shows how many you used, for example **Check now (1/3 today)**, and the count starts again at midnight in your workspace's time zone. Each person starts the campaign only once, so someone Kerux already saw isn't counted as new. Your account's time zone is taken from the browser of whoever connected the account. To change it, click **Connect accounts**, then **Manage** on the account's row and **Settings: hours, limits, pacing**, and pick the **Timezone**. ## Why some things take a while LinkedIn announces messages, new connections and new followers, so Kerux gets them as they happen. It doesn't announce invitations you receive or profile views, so Kerux checks for them on a schedule. Each kind of check is limited to about 100 a day per LinkedIn account. On a weekday the schedule above uses about 66 checks for invitations and about 66 for profile views, well under that. Checks are spread over your daytime, when someone can act on them, and slow down at night, when a person would be asleep. That keeps your account safe and leaves room for what matters most: sending your invitations and messages. See [Understanding limits](/help/account-safety/understanding-limits.md) for how these limits work. ## Your campaigns never wait for these checks Before a campaign sends a message, Kerux checks that conversation for a new reply, whatever the schedule above says. If the person already answered, the message isn't sent and the reply is handled like any other. > [accordion] A profile view or invitation hasn't shown up yet > > Check the time in your account's time zone. With a campaign that starts from that event, give it up to 15 minutes during the day (30 on weekends). From 10 PM to midnight it can take up to an hour, and from midnight to 7 AM up to 2 hours. Without such a campaign, a new invitation shows in the inbox's **Invitations** tab within about an hour on weekdays (up to 2 hours on weekends and from midnight to 7 AM). LinkedIn only shows the full list of profile viewers to **Premium** accounts, and anonymous viewers never appear. > [accordion] A new connection shows up hours later > > LinkedIn sometimes takes up to 6 hours to report that an invitation was accepted. Kerux starts the next step as soon as LinkedIn reports it. > [accordion] LinkedIn asked Kerux to slow down its checks > > When LinkedIn asks Kerux to slow down for one kind of check on an account (for example invitations received), that check is skipped and Kerux tries again at its next scheduled time, by itself. Campaigns keep sending, and replies and messages keep arriving. See [Understanding limits](/help/account-safety/understanding-limits.md). > [accordion] The automation says Not checking, or that the last check failed > > The line under an **Invitation received** or **Profile view** automation says why Kerux isn't checking: > > * **Not checking: the LinkedIn account is disconnected** or **is paused**: reconnect or resume it in **Connect accounts**. Checks start again by themselves. > * **Not checking: no LinkedIn account is connected**: connect one, or pick another account for the automation. > * **Last check ...: LinkedIn asked to slow down**: Kerux waits and checks again at the next scheduled time. Nothing to do. > * **Last check ...: LinkedIn needs the account to sign in again**: click **Fix** on the account's row in **Connect accounts**, then **Reconnect**. > * **Last check ...: LinkedIn didn't answer** or **Last check ... failed**: Kerux tries again at the next scheduled check, by itself. > > At night and on weekends the next check shows **(night: less often)** or **(weekend: every 30 minutes)**: that's the schedule above, not a problem. > [accordion] Check now is greyed out or says I used today's checks > > Each automation has 3 manual checks a day, and Kerux doesn't check again within a minute of the last check (**Checked less than a minute ago. Try again in a minute.**). When the 3 are used, you see **You used today's manual checks. Kerux keeps checking on its schedule.** Nothing is lost: the schedule above goes on by itself. > [accordion] Check now says LinkedIn didn't answer > > LinkedIn didn't answer that check. Kerux tries again at the next scheduled check, by itself. If it says **No LinkedIn account to check**, connect or resume a LinkedIn account used by the automation. > [accordion] Can Kerux check more often? > > Not without risk to the account. The checks go through LinkedIn, and checking much more often than a person would is one of the things LinkedIn watches for.
