Limit on number of emails that can be sent from free Gmail account?

I need to send the same email with a Microsoft Word 2016 attachment to around 4,800 different email addresses.

These are all email addresses that have either emailed me or that I have emailed in the past.

I will be emailing around 100 of these email addresses each time until I have emailed all 4,800 email addresses using my free email account which is set up in Outlook 2016.

Does Gmail have a limit as to how many emails addresses can be emailed over a certain time limit (such as a day) before they will halt the emails (suspecting that spam is being sent)?
