Llevo usándola un tiempo, buena extensión, con un gran catálogo de plantillas modificables
Marca error en el estado de importación de todas mis listas
Too many problems with this extension. 1. There is no customer support available even though the welcome email says "email back for any support" but the email keeps bouncing back. 2. Navigation is not very friendly. 3. Not sure if I can trust the delivery of emails, I tried using few personal emails to check the delivery and only 1 out of 4 emails received the email whereas the report showed delivered for all 4 emails. I hope the creators take this seriously instead of only getting to sign up customers for paid plan. Guys, please use the free version first instead of signing up for the paid version straightaway.
I can send email marketing campaigns directly on my Gmail account and it's easy to import email lists and personalize each email. This saves me a lot of time and I can follow-up on emails with the reporting tool.
Finalmente un sistema che funziona per mandare newsletter, riesco a creare bei messaggi e a spedirli a tutti i contatti senza problemi di invio, grazie!
Muy fácil de usar, rápida resolución de problemas
Muy buena extensión para enviar emails
Muy buena extensión para enviar emails sin complicaciones. Me encanta el editor, que permite crear diseños profesionales y resulta muy fácil importar los destinatarios. Recomendada.
Really easy and powerful email marketing tool. Huge template catalog and great editor embedded inside Gmail.
Muy fácil de usar y con un editor que permite muchas opciones a la hora de personalizar el diseño de los emails, algo que había echado en falta en otras aplicaciones parecidas.
