MIXED_ES Too many es are not es

I sending emails using PHPMailer and SpamAssassin is tagging it * 3.3 MIXED_ES Too many es are not es What does it mean? What is "es"? How to fix?

Spamassassin errors are often unhelpful! The source for that rule suggests it's to do with too many letter 'E's that are not "regular" letter Es, for example any of éèëêēĕėëẻěȅȇẹȩęḙḛềếễểḕḗệḝɇǝⱸ. It's to do with your content, not PHPmailer.

No cuentes demasiado de tus amigos. Do not trust too much in an enchanting face. No confíes mucho en una cara encantadora.

Is your plaintext version of the email in a different language than your HTML content?

Like Synchro said, it is caused by different kind of E's using diacritics. If the mailing is recognized by SpamAssassin as being "English" and the HTML content is actually in another language that makes use a lot of those ES, it can result in this message.

Muchos de mis alumnos me preguntan cuál es la diferencia entre TOO MUCH y TOO MANY en inglés. En el video expliqué que en español sólo se usa DEMASIADO. No estoy cien por ciento en lo cierto: se usa “demasiado” y “demasiados”. “Demasiado” es singular (sin la “s” al final) y “demasiados” es plural (con Read More

However, just like water, sugar, and love, money can be used as a countable noun to express a slightly different idea. Just like the British waters may be dangerous, you can put three sugars in your coffee, and many people have had several great loves in their lives, “moneys” or “monies” (the possible plural forms of money) may be used to talk about several sources or types of money.

Landlord-tenant laws generally fall under the jurisdiction of individual states. However, many state laws are very similar in scope, so much so that renters and landlords throughout the U.S
