MailHog VS SendGrid

Mailhog

hey HN, I recently published an article going deep into email previewing (in Ruby on Rails, but I think it's relevant beyond Rails).

MailCatcher (https://github.com/sj26/mailcatcher) and MailHog (https://github.com/mailhog/MailHog) are super handy and easy to run locally. Both spin up an SMTP server which you can direct mail to, and give you a nice web interface to browse mail and preview it.

Happy to answer any question! thanks, harrison

https://github.com/mailhog/MailHog This is set up for our test environments. Worth looking into

Does it say it's being send on localhost or on production? How is it "saying" it's being sent. We just setup mailhog to test emails for local development.

They should definitely invest in a chaos monkey (like Jim https://github.com/mailhog/MailHog/blob/master/docs/JIM.md)

depends on the infrastructre setup, but if you're able to specify smtp server the backend will use you can you something like https://github.com/mailhog/MailHog or https://github.com/rnwood/smtp4dev to catch any sent email, regardless of email address and read it via the respective api. Both mailhog and smtp4dev have decent api documentation.

There’s a number of resources ready to work with Go that you can utilize. Mailgun offers its own SDK for Go. SendGrid also comes with its own community-driven Go library. If Mailjet is your choice, you’ll also find numerous code samples for Golang in their REST API docs. If you prefer other platforms, you’ll likely find other user-made libraries to make integration smoother.

You're right on both of these, and I'm not settled on this at all. Struct initialization and element setting are something I haven't landed on yet for larger structs. Personally, I like the pattern like sendgrid uses for struct initialization (examples here). Using the context of my repo, seems like if they are just initializing a struct, they'd use NewMovie and if they are actually adding logic as part of the struct initialization, they'd use NewMovieInit (e.g. in their repo, NewV3Mail and NewV3MailInit).

the email package is sendgrid go client https://github.com/sendgrid/sendgrid-go For the attachment it takes a based64 encoded string Ex:

I like https://github.com/sendgrid/sendgrid-go for Twilio's Sendgrid. I got some good ideas from it - I like the way they do initializers and give you already initialized maps and slices, etc.
