HOW IT WORKS
Use Google, Microsoft, or compatible custom SMTP/IMAP accounts that you own or are authorized to connect.
Complete the connection for your email provider so the account can be used for campaigns and campaign replies.
Choose the connected accounts for your campaign. Respect provider limits and review replies together in Unibox.
Unlimited connections does not mean unlimited sending. Your email provider’s restrictions, account health, and BoostServ’s safeguards continue to apply.
Google, Microsoft, and compatible SMTP/IMAP email accounts. You need to own the account or be authorized to connect it.
Yes. Connected Senders uses email accounts hosted by your existing provider. Managed Mailboxes uses BoostServ’s BoltMail infrastructure on domains you own and is included with Flex and Pro.
No. Flex and Pro remove the limit on the number of external connections, not the sending allowance. Monthly plan limits, provider limits, and sending safeguards still apply.
