Would the server crash if I send large attachments in mailgun using images inside the server?

Question

I want to send about 80mb of 18 files from the server as an e-mail attachment in mailgun/node.js to about 1,000 people, I feel like this would be an overload on a $5 digital ocean server considering the number of requests and the size of the files. What do you recommend I do?

Hi there,

It is really hard to say yes or no, but what you could do is separate the task into chunks, so rather than sending 1000 emails, you could do this in 10 runs * 100.

You could also add a swap file so that you could have some extra memory buffer:

Hi Bobby, thanks for your reply.
The e-mails will be sent once the user registers, it won’t be 1,000 at the same time, but we’re expecting a large number of registration once we start advertising. I’m sorry, I wasn’t very clear in my post.

  Hi there,
  
  If the registrations are spread throughout the day, it should be ok I believe. But if you get the 1000 people visiting the site at once, then it might be a problem.
  
  What I could suggest in this case is to run a load test and see how your website and server behave:

  This will give you some information on whether you might have to upgrade.
