Provider limits and account care

• Full SMTP + IMAP host, port, and encryption delivered after payment.
• Webmail username and current password when the webmail add-on is selected.
• 30-day money-back guarantee on every premium SMTP purchase.
• Free replacement if a purchased account is blocked or becomes unusable — replacement guarantee included.
• Change every password before importing the accounts.
• No provider guarantees a fixed sending allowance. Automated anti-abuse controls may lower capacity or suspend abnormal traffic.

LocalSMTP’s pacing controls help reduce sudden spikes, but no software can guarantee inbox placement, prevent every provider block, or guarantee permanent third-party account availability.
