problem sending emails from HubSpot

Good afternoon.
There was a problem sending emails from HubSpot since 05/30/2022.
My HubSpot account is linked to google mail, And when I’m sending letters through HubSpot, they are blocked and do not reach the addressee. But when sending from Google mail itself, there is no such problem.
At first, this problem was only with the first letters for mailboxes that did not contact through HubSpot. But now, all the emails that I send through HubSpot are blocked by Google mail.

Hi @MSavchuk

Thank you for reaching out!

When you say ‘blocked’, could you clarify more exactly? Do you get an error message, an error code from Gmail? Can you share that here?

The more information, screenshots, and details you can provide the better we can assist!

Thank you!

Best
