Yamm es una excelente herramienta y el servicio de atención es muy bueno. Les escribí con una consulta sobre mi suscripción, qué necesitaba cambiar, y a los pocos minutos ya me habían contestado y hecho la gestión necesaria. Además, al par de día me volvieron a escribir para asegurarse que todo estaba en orden.

After shopping around for add-ons for mail merging I landed on YAM and couldn't have been happier with the user-friendly programming and the ease of use. I left the job I was using it for so I needed to cancel my subscription but it was through my work email but on my personal bank card. I messaged support and was fortunate enough to talk to Lex. Lex responded almost immediately and took care of my subscription right away without any headache. Will definitely be a returning customer if that add-on is needed again.
