Creating multiple inboxes in Seamless.AI using Connect

To maximize deliverability, response rates, and outreach scale, you can connect multiple email accounts to Connect. This article is designed to help you get the most out of Seamless.AI Connect by showing how to safely scale your outreach. Connecting multiple emails not only allows you to send more messages, but also helps protect your sender reputation and ensures your campaigns land in more inboxes.

Reminder: How to Connect an Email

Inside your settings via the Emails tab, click “Connect Email” to begin the setup process. A window will appear, giving you the option to connect with a Gmail or Outlook account. After selecting your preferred email provider, a new window will open prompting you to choose the email account you want to connect to. 

You will need to review and agree to the Privacy Policy before proceeding. Once confirmed, allow Seamless.AI access to enable email functionality within the platform. Once completed, your email will be officially connected, and you’ll be ready to send emails directly through Seamless.AI’s platform.

Why You Want to Do This

Connecting multiple email accounts is one of the best ways to scale your outreach effectively. Each inbox has a daily sending limit, and if you only rely on one account, you may hit that cap quickly and delay your campaigns. By spreading messages across multiple inboxes, you can send more emails in the same day without hitting provider restrictions. At the same time, distributing volume helps maintain a strong sender reputation, reducing the risk of emails being flagged as spam and ensuring better deliverability over the long term.

Best Practices for Multiple Emails

  • Distribute Sending Volume: Keep email sends between 150–250 per inbox per day to avoid overloading one account.
  • Use Multiple Domains: Set up variations like @company.com, @company.co, or @getcompany.com to spread risk.
  • Segment Campaigns by Inbox: Assign different campaigns or reps to different inboxes for better organization.
  • Keep Branding Consistent: Maintain the same professional signatures, disclaimers, and tone across inboxes.
  • Monitor Performance: Track deliverability, bounce rates, and engagement by inbox to spot issues early.

Warming Up New Email Accounts

  • Start Small: Begin with 5–10 emails per day in the first week.
  • Increase Gradually: Add 10–20 more emails per day over time until you reach full sending capacity.
  • Target Trusted Contacts: Send early messages to coworkers, partners, or known contacts who will reply.
    Encourage Replies: Prioritize conversations and back-and-forth engagement to strengthen reputation.
  • Consider Warm-Up Tools: Use automation tools to simulate natural email activity and speed up the process.
