Contact WhichMailer
The short answer
Write to contact@whichmailer.com for anything on the site: an outdated price, a factual error, a platform we should cover or a question a guide did not answer. Price corrections are the most useful mail we get.
What to include
For a price correction, the page URL on WhichMailer plus the official page showing the current amount gets it fixed fastest. For platform suggestions, tell us the situation it serves better than the nine we already cover.
