## Connection Requests
Send connection requests to people outside of your network and invite them to be part of your network. You can send \~100 connection requests per week, or \~400 connection requests per month.
{% hint style="info" %}
Your connection request limit does not change by much, regardless of whether you have a free account or Sales Navigator account.
{% endhint %}
{% hint style="info" %}
Connection requests are limited to 300 characters.
{% endhint %}
## Follow Up Message
You can send follow up messages to people who accept your connection requests. There is no limit on follow up messages, but you can only send them to people within your network.
## Paid inMail
Linkedin gives you a certain number of inMails per month that can be used to send to people outside of your network.
{% hint style="info" %}
inMail is a paid Linkedin feature available with a Sales Navigator subscription.
{% endhint %}
## Free inMail to Open Profiles
Free inMails do not count toward your stated inMail limit - think of them like bonus messages, but they can only be sent to people with an open profile. You can send up to 900 Free inMail messages per month.
What is an open profile?
An open profile is a privacy setting for a Linkedin profile, where they have chosen to make it so anybody can message them, rather than only allowing people they are connected with to message them.
{% hint style="info" %}
Around 30% of Linkedin profiles are "Open."
{% endhint %}
{% hint style="info" %}
Free inMails still require a paid Sales Navigator subscription to send.
