There are different ways to send mass email in Gmail, depending on the number of recipients and the level of personalization. Here are some ways:
1. Compose a new email and input your contact addresses, using the BCC option to hide them from each other. This is a good option if you have a small number of recipients and don't need to personalize the email.
2. Create a mailing list or a label and select it when composing a new email. This is a good option if you have a larger number of recipients and want to personalize the email.
3. Use Google Drive and an extension like GMass or YAMM to create a Google Sheet with your contacts and send personalized emails. This is a good option if you have a large number of recipients and want to personalize the email.
Sending mass email in Gmail has some limitations, such as the maximum number of recipients per email and the maximum number of emails per day.
