ruby - How can I place my email processes/routine outside of my frontend server (Rails 3.2/devise/sendgrid/heroku) -


in order free frontend server, i'd place requests sent sendgrid ( authentificaiton, confirmation, passwiord reset , transactionnal emaisl such "no visit long time" email , daily email send.

it's necessary plan need keep memory , power of main server web app , includes displaying pages possible. we'd keep emails routines eating of our main web app server memory/power.

now on 1 single server (on dyno on heroku) (plus database).

as plan have lot of traffic on front end, think make sense create dyno reserved email process (let's call "email server/dyno".

but should talk app , database

  • for ex if user signs up, main dyno web app has send message "email server"

  • another ex: i'll have access same database use cron see if need send email if user subscribed 8 weeks ago , and has never signed in on website.

so keep short,

how can create set server deal emails

should put same gems , environment

how can "email server" talk main web app , database?

any advice or resource on web explains how this?

the way own apps resque , resque mailer. resque queue based on redis can run using heroku worker. here resources might started that:

resque mailer plugin lets background emails actionmailer using resque. can find more details on github readme:
