What the Mails.so connector can do
Mails.so checks email addresses for deliverability and risk, supporting both one-off checks and bulk list validation. A growth or lifecycle Space in type.com can ask the agent to validate a single address before a one-to-one send, kick off a bulk check on an imported list, or pull back the results once a batch finishes processing, keeping list hygiene part of the campaign workflow.
