• Message Character Limits:
  • Body: 32768

Account Setup

Creating an account with SendGrid is free of charge and can be done through their main page.

Once you have an account and access to your dashboard. You will need to ensure you’ve correctly authenticated your domains with them; this is done in the Sender Authentication section of your dashboard. You get here by clicking on Settings > Sender Authentication from your dashboard.

The last thing you need is to generate an API Key with at least the Mail Send permission. This can also be done through your dashboard in the API Keys section of your dashboard. You can get here by clicking on Settings > API Keys

Syntax

Valid syntax is as follows:

• {schema}://{apikey}:{from_email}
• {schema}://{apikey}:{from_email}/{to_email}
• {schema}://{apikey}:{from_email}/{to_email1}/{to_email2}/{to_email3}

Template support is also supported as well, You just need to specify the UUID assigned to it as part of the URL:

• {schema}://{apikey}:{from_email}/{to_email}?template={template_uuid}

If you want to take advantage of the dynamic_template_data variables, just create arguments prefixed with a plus (+); for example:

• sendgrid://{apikey}:{from_email}/{to_email}?template={template_uuid}&+{sub1}=value&+{sub2}=value2

Parameter Breakdown

Variable	Required	Description
apikey	Yes	The API Key you generated from within your SendGrid dashboard.
from_email	Yes	This is the email address will identify the email’s origin (the From address). This address must contain a domain that was previously authenticated with your SendGrid account (See Domain Authentication).
to_email	No	This is the email address will identify the email’s destination (the To address). If one isn’t specified then the from_email is used instead.
template	No	You may optionally specify the UUID of a previously generated SendGrid dynamic template to base the email on.
cc	No	The Carbon Copy (CC:) portion of the email. This is entirely optional. It should be noted that SendGrid immediately rejects emails where the cc contains an email address that exists in the to or the bcc list. To avoid having issues, Apprise automatically eliminates these duplicates silently if detected.
bcc	No	The Blind Carbon Copy (BCC:) portion of the email. This is entirely optional. It should be noted that SendGrid immediately rejects emails where the bcc contains an email address that exists in the to or the cc list. To avoid having issues, Apprise automatically eliminates these duplicates silently if detected. If an identical email is detected in both the CC and the BCC list, the BCC list will maintain the email and it will drop from the CC list automatically.

Global Parameters

Variable	Description
overflow	This parameter can be set to either split, truncate, or upstream. This determines how Apprise delivers the message you pass it. By default this is set to upstream 👉 upstream: Do nothing at all; pass the message exactly as you received it to the service. 👉 truncate: Ensure that the message will fit within the service’s documented upstream message limit. If more information was passed then the defined limit, the overhead information is truncated. 👉 split: similar to truncate except if the message doesn’t fit within the service’s documented upstream message limit, it is split into smaller chunks and they are all delivered sequentially there-after.
format	This parameter can be set to either text, html, or markdown. Some services support the ability to post content by several different means. The default of this varies (it can be one of the 3 mentioned at any time depending on which service you choose). You can optionally force this setting to stray from the defaults if you wish. If the service doesn’t support different types of transmission formats, then this field is ignored.
verify	External requests made to secure locations (such as through the use of https) will have certificates associated with them. By default, Apprise will verify that these certificates are valid; if they are not then no notification will be sent to the source. In some occasions, a user might not have a certificate authority to verify the key against or they trust the source; in this case you will want to set this flag to no. By default it is set to yes.
cto	This stands for Socket Connect Timeout. This is the number of seconds Requests will wait for your client to establish a connection to a remote machine (corresponding to the connect()) call on the socket. The default value is 4.0 seconds.
rto	This stands for Socket Read Timeout. This is the number of seconds the client will wait for the server to send a response. The default value is 4.0 seconds.
emojis	Enable Emoji support (such as providing :+1: would translate to 👍). By default this is set to no. Note: Depending on server side settings, the administrator has the power to disable emoji support at a global level; but default this is not the case.
tz	Identify the IANA Time Zone Database you wish to operate as. By default this is detected based on the configuration the server hosting Apprise is running on. You can set this to things like America/Toronto, or any other properly formated Timezone describing your area.

Dynamic Template Data

Templates allow you to define {{variables}} within them that can be substituted on the fly once the email is sent. You can identify and set these variables using Apprise by simply sticking a plus (+) in front of any parameter you specify on your URL string.

Consider the following template: d-e624763c71314ea2a1fae38d7fa64a4a

This is a test email about {{what}}.

You can take a mapped variable on a SendGrid template
and easily swap it with whatever you want using {{app}}.

In the above example, we defined the following variables: what and app.

An Apprise URL might look like:
sendgrid://myapikey:noreply@example.com?template=d-e624763c71314ea2a1fae38d7fa64a4a&+what=templates&+app=Apprise

The above URL would create the following:

This is a test email about templates.

and easily swap it with whatever you want using Apprise.

Examples

Send a SendGrid notification:

# Assuming our {apikey} is abcd123-xyz
# Assuming our Authenticated Domain is example.com, we might want to
#  set our {from_email} to noreply@example.com
# Assuming our {to_email} is someone@microsoft.com
apprise -vv -t "Test Message Title" -b "Test Message Body" \
   sendgrid:///abcd123-xyz:noreply@example.com/someone@microsoft.com
