rails sendgrid send email in schedule time -

i using sendgrid sent email in ror application. uncertainty can compose email , email must deliver user in particular schedule time, given user @ time of compose.

for eg.

to : yyyy@gmail.com

subject : hi

message : how ?

msg deliver time : 05-11-2014 7.30 pm

is alternative in sendgrid (or) want store details in db , utilize cronjob solution ?

thanks in advance

if window under 24 hours, can utilize sendgrid's smtp-api scheduling parameters. supply unix timestamp when email delivered.

from docs:

{ "send_at": 1409348513 }

if window exceeds 24 hours, worker / cron best solution.
