What usually comes up before bringing your list over. Didn't find yours? Talk to us.
No. Campaigns, automations and segments are built on screen. And if you lack the team or the time to run your list, at OpEx we run your retention for you.
Yes. You import your contacts by CSV, and the list stays yours: import and export whenever you want. Before the first send, Sentinel checks every address.
You don't pay per contact: the price is per sending IP and per email processed. There is no public price list; talk to us and the proposal is sized to your operation.
Yes. Sending IPs live in the panel's IP Management, and if your volume calls for an IP of your own, we work that out with you in the conversation.
Bounce Guard tracks rejections while the send goes out: it warns from 2% and cancels from 5%, at the default limits. Google Postmaster's spam rate and SPF, DKIM and DMARC are in the panel itself.
Yes. The account is split into projects, each with its own sending timezone, and campaigns, automations, segments and push live in the same panel.
Yes. Leads come in through the public API (/v2/leads), and the MCP connector lets you operate the platform through Claude, asking in plain English: core.mcp.everinbox.com.br/mcp.
Whoever unsubscribes stops receiving your sends, and every unsubscribe shows up in the reports. Consent belongs to whoever captures the lead: it comes in through your form, and you are the one who asks for their permission.
