Attachment limits can matter for the files you share, while Gmail and Outlook integration indicate how the tools relate to existing email setups. Free-plan availability and paid-from pricing offer cost context. Mailvelope and DataMotion Secure Email Exchange lead the ranking, with FlowCrypt also among the first entries. Weigh the listed features against how you send protected messages.
