Rolling out Clay to 100+ reps is a completely different beast than solo usage. You're smart to think about controls upfront.
For enrichment requests, most teams I've seen use either Salesforce forms or dedicated Slack channels. The Slack approach works well because reps can drop lists and get notified when data's ready. Some teams use Airtable forms that feed into Clay tables — gives you better request tracking and approval workflows.
Credit spend control is critical at your scale. Interface tables work, but they're clunky for rep workflows. Better approach: set up dedicated enrichment tables with pre-approved waterfall logic, then use Clay's API to process batches. You can build simple request limits this way and track spend by rep/team.
For the sequencer rollout, Clay's permissions are pretty limited. You can't really lock reps into just sequencer views — they'll see the full table structure. Most teams handle this by creating template tables with the enrichment already done, then letting reps clone and customize sequences.
The email editing piece works fine, but managing Google Workspace connections for 100 reps gets messy fast. Consider having reps review/edit in Clay but push final sequences to your existing email tool (Outreach, Salesloft, etc.) for sending. Much cleaner from a deliverability and compliance standpoint.
Budget at least 2-3 weeks for proper training rollout. Clay's learning curve hits hard when reps can't troubleshoot their own waterfall issues.
