umm looks cool but stops working.
Really good extension for writing newsletters and sending to subscribers BUT..... every time I open Gmail the extension appears in my browser at the top, but doesn't show in Gmail. Only solution I've found is to uninstall the extension then reinstall it :/ comments on how to resolve this would be most welcomed (using the Free version).
Easy to use. Lot of templates. The template editor is fair enough. Besides, we can track some basic statistics about the campaigns. Sometimes I came with problems when trying to save a template after modification. Other shortcoming is the high reponse delay when opening the templates sections. I couldn´t import my gmail contact list (too slow or even infinite loop). Overall experience is good.
Está bien si eres un pequeño negocio o particular. Haces una plantilla en excel y la subes. Envías la plantilla que quieras a esos contactos que has creado. Pero tiene que ser EXACTAMENTE como ellos te dicen; las cuadrículas y el relleno de ellas. Por ejemplo, si pones en Dirección una calle sin número ya no se envía nada. A veces puede complicar un poco todo eso porque puedes tener un pequeño "fallo" para el programa y no te deja enviar nada. Las plantillas las puedes hacer como quieras y tiene bastantes cositas para poner; imágenes, botones, texto, etc.
Desde el principio que esta con problemas, no carga bien las paginas y uno tiene que esperar mucho tiempo o reiniciar la pagina de Gmail constantemente para que se muestre como debe, y despues lanza mas problemas para subir el archivo con la lista, y por ultimo el correo de prueba ni siquiera llega al correo puesto, a pesar de ocupar otros correos de prueba. En general, no me gusto la plataforma y tampoco me ha funcionado bien.
Esta extensión es muy completa y apropiada para campañas de email dentro del entorno G-mail. El editor de plantillas es super excelente. Me gustaría recomendar cambiar de posición la opción de "guardar" de las opciones "copiar y eliminar", jajajaja, ya perdí una plantilla de newsletter porque en vez de "guardar" le dí "copiar".
Presque parfait ! Manque quelques fonctionnalités pour la gestion des listes de contacts (j'imagine que ça arrivera) mais qu'il y a moyen de contourner via l'import direct depuis les contacts Google. Pour le reste, un vrai bonheur ! Un souci au début, mais qui a été réglé en 48h avec un beau geste commercial en plus. A tester sans hésiter.
Works, finally no limits on the newsletters I want to send. Very effective, good job!
Fácil de usar y muy intuitivo. Para mi lo mejor es el editor, se pueden crear plantillas súper bonitas muy rápidamente, y además hay un montón de diseños para elegir!
Es súper fácil mandar newsletters con esta aplicación, hay un montón de plantillas para elegir y luego puedes cambiarlas como quieras, el editor es muy intuitivo. Además, está en español, que es un plus
