hard to verify domain unble to verify
I have many technical difficulties with this extension & support provides little to no help. Frustrating to create new templates as it is slow to load...tried on multiple different computers & search engines. Mostly use Chrome & a MacBook Pro. Looking to change email marketing platforms once my subscription expires.
We've just sent our first campaign. Very impressed so far and like how easy it is to use and love the how integrated it is to google. Its a brilliant tool. Im also looking forward to being able to schedule campaigns as well - great feature!
Hi guys, I have tried your free subscription and see that you have a great product. Now, I want to subscribe to your Basic plan, but after entering my card details the pay button has been rotating like for ages. I have tried it 2 times. Is there any other way I can go about this? Please reply as soon as possible. Thank you. Paul
Desde hace mas de una semana mi cuenta se encuentra bloqueada, el chat de soporte incorporado en la aplicación es meramente decorativo, nunca me ha contestado nadie. Despues de mucho insistir he conseguido que me contesten por mail pero no me han solucionado nada y me dicen que mi cuenta esta bajo revision por contenido inapropiado y no me dan mas detalles. Y pasan los dias y sigo esperando... Nota: que nadie se moleste en llamar por telefono ya que nunca contesta nadie ACTUALIZADO 20/11/23 El problema continua incluso a peor si cabe. Supongo que mi caso lo esta gestionando el becario de la empresa porque no entiendo nada, ahora me han activado de nuevo la cuenta pero sigo sin poder utilizarla ya que me han limitado los envios a un numero muy bajo que es el caso de las cuentas de gratuitas o de demo, pero mi cuenta es de pago...
No option to add attachment. even pdf file.?
Had a lifetime plan from Appsumo. I like the app because it is very easy to use. My site is fully verified for ownership, DKIM, and SPF. However, some emails are still sent directly to the spam folders.
Para poder utilizar esta extensión es necesario conceder PERMISOS EXCESIVOS, como por ejemplo poder acceder/leer/descargar a toda la información que almacenas en Google Drive. En otras extensiones similares (Ej: MailMeteor) esto no es necesario, por lo que la excusa de que es necesario para que la aplicación funcione no es verdad.
loved it
Very simple to use yet very much powerful for bulk email campaign and newsletter, Loved It. Thank you Gumbamail Team.
