Connect a mailbox

HeyInvest sends email campaigns from your own Gmail or Google Workspace account. Investors see the email coming from you, and their replies land in your Gmail as usual.

Connect your Google account

1. Go to Inbox in the sidebar, then the Mailboxes tab.
2. Click Connect Google account.
3. Sign in to Google and allow both permissions:
   • send email as you, and
   • read replies to the emails HeyInvest sent, so follow-ups stop when someone replies.
4. You're brought back to HeyInvest with a message that your mailbox is connected.

Your Google password never touches HeyInvest. You can connect as many Google accounts as you like. Each mailbox can only be connected by one person.

Microsoft 365 / Outlook mailboxes aren't supported yet.

Mailbox settings

Click Settings next to a mailbox to change:

• Daily limit: how many emails it sends in 24 hours (1 to 100, default 40). For a new mailbox, start around 20 and raise it slowly.
• Time zone for the sending window: campaigns send during working hours in this time zone.

Click Test to check the connection works, or Disconnect to remove the mailbox. Disconnecting a mailbox stops the campaigns that send from it.

Built-in safety limits

To protect your mailbox's reputation:

• each mailbox sends at most its daily limit (never more than 100 a day),
• emails go out on weekdays between 8am and 6pm by default,
• emails are spaced 2 to 6 minutes apart,
• a sequence stops automatically when someone replies or an email bounces.

If a mailbox needs to reconnect

If Google signs a mailbox out, you'll see a Reconnect status and a banner on your campaigns. Click Reconnect on the Mailboxes tab. Sending picks up where it stopped. Nothing is lost.

If connecting doesn't work
