Someone signs up with a 10-minute email address, your agent sends out a beautiful welcome sequence, and then the email bounces immediately. That's a one-way ticket to getting flagged by providers like SendGrid or Mailgun, which ruins your sender reputation for everyone else. This Connector stops that cycle before it starts. It lets your agent check every incoming email against a massive, community-maintained list of known disposable providers. Instead of guessing, your agent gets a clear yes or no on whether an address is legitimate. It's a simple way to ensure that only real people end up in your Salesforce or HubSpot instances. By plugging this into your workflow via the Vinkius catalog, you give your agents a filter that keeps the junk out and the quality in. ## Tools ### check_disposable Pass an email address to see if it's from a temporary provider. This helps your agent decide whether to accept or block a new lead. ## Prompt Examples **Prompt:** ``` Check if this new lead's email `user@mailinator.com` is a throwaway address. ``` **Response:** ``` **Disposable Email Validation:** Domain is disposable. **Action Recommended:** BLOCK. ``` **Prompt:** ``` Is `ceo@vinkius.com` a legitimate corporate email? ``` **Response:** ``` **Disposable Email Validation:** Domain is NOT disposable. **Action Recommended:** ALLOW. ``` **Prompt:** ``` Validate this CRM contact list item: `tester@10minutemail.com`. ``` **Response:** ``` **Disposable Email Validation:** Block action recommended. ``` ## Capabilities ### Identify throwaway addresses Instantly flags emails from known temporary providers. ### Protect sender reputation Prevents bounces from damaging your mail provider standing. ### Clean CRM data Stops fake leads from polluting your customer database. ### Validate leads locally Checks domains against a local list without external API calls. ### Automate lead rejection Allows your agent to skip low-quality signups automatically. ## Use Cases ### Blocking fake signups from web forms A lead signs up with a 10minutemail.com address. The agent uses check_disposable first and blocks the signup before it hits your CRM. ### Scrubbing bulk lists before import You're importing a list into Salesforce. The agent validates every email to scrub the list of throwaway accounts before the import starts. ### Filtering real-time webhooks Bots are flooding your signup form. Your agent checks each entry and only proceeds if the email is a legitimate domain. ### Protecting cold outreach domains To avoid high bounce rates on a new domain, the agent verifies every target email against the disposable list before sending. ## Benefits - Stop high bounce rates by using check_disposable to catch temporary addresses before you send a single email. - Keep your CRM clean by ensuring only legitimate leads from real domains get saved to HubSpot or Salesforce. - Shield your mail provider status because your agent won't trigger the spam flags that come from sending to dead accounts. - Work faster with local validation since your agent doesn't have to wait for external API responses to verify a domain. - Improve lead quality by allowing your agent to automatically reject signups from providers like Mailinator or 10MinuteMail. ## How It Works The bottom line is you get a reliable filter that keeps fake emails out of your marketing sequences. 1. Connect the Connector to your AI client through the Vinkius dashboard. 2. Have your agent pass an email address to the check_disposable tool. 3.
