Pochta is an open source cli application to help developers send test emails. Conventionally you need an email client or some form of API integration. Pochta eliminates that need and helps enhance your email testing workflow.


  • MJML support
  • Multiple email service providers
  • Multiple cdn integrations
  • Smart cache for image uploads
  • Contact management
  • Screenshots
  • build and export
  • Minify HTML

$ npm i pochta-mjml -g 

Example Usage

Below are a few basic examples, run $ pochta help for more details.

Send an email:

$ pochta send 

Create a profile:

$ pochta profiles new 

Create an esp:

$ pochta esp new 

Create a contact:

Create an image hosting provider:

$ pochta hosts new 

Take a screenshot:

$ pochta capture 

Take a screenshot (advanced example):

  • The example below will generate 320 and 800 pixel wide screenshots @3 device scale factor. The output will be in the pdf format.
$ pochta capture -w 320 -w 800 -d 3 -f pdf

Why Pochta?

If you are using MJML app you can use MailJet integration to test your emails. However, neither your local images get hosted on MailJet server, nor you get an option to embed images as inline attachments or get to host on your preferred CDN directly.

Of course, these limitations can be overcome by exporting html manually and/or updating image sources but, if your assets are constantly changing during the development, then this can be a tedious task.

If you don't have a MailJet account than you're probably relying on Outlook 2010's stationary feature. Outlook is notorious for changing html content and will mess up your layouts in unintended ways.

Pochta eliminates this limitations and you can have multiple CDN and ESP for your need. Additionally, you can build and export your email with a CDN provider for the e-blast distribution.

Pochta also has a built in capture feature which can take screenshots of your email for various devices widths and scale factors.

Below are some email and CDN service providers that are currently supported by Pochta:

Email Service Providers

  • SendGrid
  • MailJet
  • Amazon SES
  • Gmail
  • Microsoft Exchange


  • AWS S3
  • Cloudinary
  • ImageKit

pochta build

Build html/mjml files and export content into a new directory

  $ pochta build

  -c, --cache=cache  Boolean flag to enable/disable upload cache

  This command generates HTML by parsing MJML/HTML and hosting images to the dedicated cdn provider. If no host selected 
  then, either the images can be embedded as Base64 or can be exported to a directory related to the generated html 

  By default the cache is disabled, meaning on each usage of this command it will try to upload images to the preferred 
  cdn provider. If you want to enable cache use with --cache=true flag.

See code: src/commands/build.js

pochta capture

Capture html/mjml screenshot and save in various format (i.e. png, jpg, pdf)

  $ pochta capture

                            export and save screenshots for each width

  This command generates a screenshot of the email and saves it under captures directory. In order for this command to 
  work a Chrome browser must be installed on the machine. The default screenshot width is 800px and will export as a 

  The default width can be overwritten with the width flag. This command supports multiple widths and it is helpful if 
  you like to capture different sizes. This is extremely helpful for responsive emails or checking email behaviour on 
  multiple sizes.

  If the dfg (Device Scale Factor) flag is set, the screenshots will result as scaled without loosing the quality. Ideal 
  for mimicking mobile devices screenshots.

  Screenshot quality and formats can be changed respectively via quality and format flags.

  The screenshot(s) will overwrite any existing files of the same names.
