Frequently asked questions.
Frequently asked questions- Which is cheaper, GMass or Outplay?
- GMass is cheaper at the entry level, starting at $30/month compared to Outplay's $39/month starter plan. GMass maintains this price advantage across its lower tiers, with its Standard plan offering unlimited contacts and campaigns. However, Outplay's AI SDR plan costs $99/month while GMass Teams (5 users) costs $175/month, making per-feature comparisons dependent on specific needs.
- Does GMass work outside of Gmail?
- No, GMass works exclusively inside Gmail and requires a Google Workspace account. This is a core architectural choice that distinguishes it from standalone platforms. If you need email outreach outside the Gmail ecosystem, GMass won't be suitable. Outplay, by contrast, works with both Gmail and Outlook, offering more flexibility for teams using different email providers.
- Can Outplay make phone calls and send LinkedIn messages?
- Yes, Outplay supports multi-channel outreach including phone calls through its power dialer with auto voicemail drop, LinkedIn automation, SMS, and chat in addition to email. This makes it a true sales engagement platform rather than just an email tool. GMass focuses exclusively on email outreach and doesn't include calling, LinkedIn, or SMS capabilities.
- Which platform has better CRM integrations?
- Outplay offers stronger CRM integration support with 9 total integrations including Salesforce, HubSpot, Pipedrive, and Microsoft Dynamics 365. GMass provides 4 integrations focused on Google Workspace tools like Google Sheets. Both integrate with Gmail and Zapier, but Outplay's native CRM connections make it better suited for teams with established sales tech stacks requiring deep CRM synchronization.
- Do both platforms have unlimited email sending?
- Both platforms offer unlimited email sending, but with different constraints. GMass provides unlimited emails across all plans but remains subject to Gmail's built-in sending limits. Outplay also offers unlimited emails on all plans, though its Starter plan limits you to 5,000 active prospects per month while Growth and Enterprise offer unlimited contacts. The practical sending volume depends on your email provider's rules and your sender reputation.
