Client for communicating with sv-email


npm install @simpleview/sv-email-client



EmailPrefix can be loaded into sv-graphql-client GraphServer to use as a client library for accessing email in GraphQL.

const { EmailPrefix } = require("@simpleview/sv-email-client");
const { GraphServer } = require("@simpleview/sv-graphql-client");
const graphServer = new GraphServer({ graphUrl : GRAPH_URL, prefixes : [EmailPrefix] });


All calls through sv-email require an acct_id and the token used requires the email.send permission on that account.

Emails sent on behalf of Simpleview or it's products should utilize the sv-all acct_id, doing so will require using an sv : true token.

Emails sent on behalf of a client should utilize the acct_id specific to that client.


Sends an e-mail or multiple e-mails. See the GraphQL schema browser for all available keys, the majority of which are self-explanatory.

There are a couple key things to keep in mind:

  • You must specify a to or a users array but not both.
    • If you want ONE e-mail to go to multiple users, such that all e-mail address appears alongside each other on the to line, the utilize the to array.
    • If you want MULTIPLE e-mails to go to multiple users, where each gets a unique e-mail with just their address in the to line, then utilize the users array.
  • If you specify cc or bcc when using the users array, then each e-mail in the users array will receive an e-mail and each will have the entries from the cc and bcc.
  • The pool_type key can be either a transactional or marketing. Depending on which is passed it will send from a different ip address in sendgrid.
    • Use the transactional pool for sending e-mails that related to a specific action performed in a system. If a user assigns a task to a user and we need to send them an e-mail, that is transactional.
    • Use the marketing pool for e-mails which are more marketing and e-mail blast like. This is for newsletter sign-up or subscription systems where a user opts-in.
    • Generally if a user can unsubscribe from the e-mail, it's marketing, otherwise it's transactional.
    • If pool_type is left blank, it will send with from the catch-all IP addresses.
  • You can pass an array of content to do multipart e-mails. If you do, the first entry in the array must be type : text.
  • The top level success boolean will only be true if all e-mails are successfully sent.
  • When debugging you can request the email field and it will return the arguments that are passed on to SendGrid's api.
  • If you have tests which send to invalid e-mail addresses, please utilize sandbox : true so that the e-mail is not sent, but you can still verify that the code to sv-email is working. This way our email reputation score is not adversely affected by sending to bogus e-mails.


If you need to send an e-mail to multiple users but want the e-mail to personalized per user, you can use the substitutions object.

In the substitutions object the key is the value you are substituting, and the value is the key that will replace it. The key name can be any value, it does not need to be wrapped in %. SendGrid does a simple string replace so if the key you choose occurs naturally, then you may get substitutions you did not plan, so please choose a unique key structure such as %key% or {{key}} or ${key}.

In the example below the key is %fname%. This will result in an e-mail being sent to oallen@simpleviewinc.com with the subject Hello Owen and an e-mail to msaladino@simpleviewinc.com with the subject Hello Michael.

	input : {
		users : [
				email : "oallen@simpleviewinc.com",
				substitutions : {
					"%fname%" : "Owen"
				email : "msaladino@simpleviewinc.com",
				substitutions : {
					"%fname%" : "Michael"
		from : { email : "donotreply@simpleviewinc.com" },
		subject : "Hello %fname%",
		body : { type : html, value : "<h1>Dear %fname%</h1><p>You are receiving this e-mail because you are totally awesome.</p>" },
		sandbox : true
	fields : `

For more information about substitutions, please see the SendGrid API documentation.
