For a few accounts, add them in Gmail (profile picture, Add another account) and switch between them, or use separate Chrome profiles. To see mail in one inbox, set up automatic forwarding. Gmail is removing Gmailify and POP "Check mail from other accounts", so do not rely on those. For many cold email mailboxes, use a unified inbox.
The right setup depends on how many accounts you have and whether you need to reply from each one.
Revbound puts replies from every sequencer mailbox in one list and answers them.

In Gmail on the web, click your profile picture, then Add another account and sign in. Switch by clicking your picture and choosing the account. Each account opens in its own tab.
Option 2: Use Chrome profiles
Create a Chrome profile for each account so bookmarks, extensions and sign-ins stay separate. This avoids the default account switching unexpectedly when you open links.
Option 3: Forward mail to one inbox
Set up automatic forwarding from each account to a main inbox, then use "Send mail as" to reply from the right address. Add filters to label mail by the address it was sent to.
Option 4: The Gmail mobile app
The Gmail app for Android, iPhone and iPad can hold several accounts, including non-Gmail ones over IMAP, with an "All inboxes" view.
2026 change: Gmailify and POP fetching are going away
Google says Gmail will remove support for Gmailify and for "Check mail from other accounts" (POP fetching) on the web. Its suggested replacements are automatic forwarding from the other provider, or adding the account in the Gmail mobile app over IMAP (Gmail Help).
Managing many cold email mailboxes
Agencies often run dozens of Google Workspace mailboxes across Instantly, Smartlead or Email Bison. Checking each one does not scale. Sequencers have their own inboxes (Instantly Unibox, Smartlead Master Inbox), but only for their own campaigns. Revbound pulls replies from all supported sequencers into one list, labels them and answers interested leads. See the unified inbox and best email client for multiple accounts.
Connect your sequencers once, and Revbound shows every reply from every mailbox in one place.
