Start with purpose-built aliases
Use dedicated aliases for billing, developer tools, newsletters, and support instead of one shared catch-all address.
mailservr lets you create aliases manually or generate them quickly so each sign-up stays isolated.
- Create one alias per service or vendor
- Add notes to aliases so you remember the original use case
- Archive old aliases instead of deleting context
Use inbox controls to find risk faster
Your inbox supports threaded conversations, full-text search, unread/starred filters, and date/address filters.
That makes it easy to spot abuse patterns, recurring senders, and stale conversations that should be closed.
- Filter by address to isolate one alias
- Search sender, subject, or message content
- Star high-priority threads and archive the rest
Block repeat senders at the alias level
When a sender repeatedly abuses one alias, block them for that specific address instead of changing your entire setup.
This limits collateral damage and helps preserve normal traffic on other aliases.
Know your sending and storage limits
mailservr enforces plan-based daily and monthly send limits, alias limits, API key limits, and attachment storage limits.
Each attachment is validated up to 100MB, so plan your workflows for predictable throughput.
