What Mailreach does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A published price above 100 mailboxes
- A price for 101 or more mailboxes
- Whether annual billing is charged up front
Where the sources disagree
We report each version rather than pick one.
- The totals printed in the page text did not match its rates, so every Mailreach figure here is calculated from the rates in the pricing page's script and not copied from a total.
