Can I send emails from my existing Gmail or Outlook?

Yes. You connect your existing email accounts (G Suite, Office 365, SMTP/IMAP) to send through Mailshake while maintaining your normal inbox look.

What's the difference between the pricing plans?

Starter is for limited email volume. Email Outreach adds unlimited sends, CRM integrations, and A/B testing. Sales Engagement adds the phone dialer, unlimited numbers, and 1-on-1 onboarding.

How do you handle duplicate prospects across campaigns?

Mailshake automatically identifies and deduplicates prospects based on email address to prevent multiple recipients from getting the same campaign messages.

What does the AI Email Writer (SHAKEspeare) actually do?

It's a fine-tuned LLM that generates email copy variants from a short prompt, suggests A/B test subjects, and can spin syntax for personalization tokens to improve deliverability.

Is there a way to track conversions from email to sales?

Yes, you can implement conversion tracking via the Mailshake.js snippet on your website or use CRM integrations to sync opportunity data back to campaign reports.
