How to forward emails from Google Apps (Gmail) to Sendgrid? - google-app-engine

I am trying to use Sendgrid as SMTP server for sending all emails from my users using Google Apps for email.
The catch is that Sendgrid requires password authentication and i couldn't find a way in Google apps Admin console to out that in (theough of coruse, there are ways to enter the SMTP server IP, but it doesn't work).

How to hook SendGrid to Free Gmail account (Not Google for work account)?
See: https://support.google.com/mail/answer/22370?hl=en
Click the gear in the top right.
Select Settings.
Click the Accounts and Import tab.
Under Send mail as, click Add another email address.
Click Add account >>
Give a descriptive name to this new "email transmitter" (e.g. "Send mails via SendGrid")
Give any email address that belong to you but not a GMAIL email (e.g myemail#mydomain.com)
Uncheck the Alias check mark
Change your SMTP to smtp.sendgrid.net
Use ports 587 for plain/TLS connections .
SendGrid username (sendgridname)
SendGrid password (sendgridpassword)
Gmail will send you a verification email to the "transmitter email" (e.g to myemail#mydomain.com)
Open your other account (mantas.hof.hefer#hhcc.org.il) and either click the link in the message Gmail sent or enter the confirmation code in the Accounts and Import section of your Gmail settings.
Whenever you want to send email from Gmail via SendGrid when you compose the email, in the “from” field select the SendGrid email (rami via SendGrid).
The will be send as like it has been send from the “email transmitter” (e.g it will send to myemail#mydomain.com).
Type the verification code and you are set.
Next time you want to compose an email from Gmail please select the field "FROM" and choose the new "transmitter email" (e.g. "Send mails via SendGrid"). Write your email and send it. It will be send via SendGrid.
If you login into your SendGrid account you can find many statistics on this email such as how many people have open this email. (https://sendgrid.com/logs/index).
The only thing that I couldn't figure is how use the SMTP protocol from GOOGLE JAVASCRIPT (not java) in order to manipulate my emails.
There are many SendGrid SMTP commands that can be added to the message headers but I couldn't figure how to do it.

The sendgrid API auth's from within the request. Simply use UrlFetch to send POST requests containing your API creds to the sendgrid endpoint.

If anyone comes across this answer as I did via a Google search, this update might help. The answer provided by #rmisegal is basically correct but you now use an API key from SendGrid.
You can setup an SMTP email API key via the SendGrid dashboard:
Log into your sendGrid Account.
Click on your account name in the top left of the dashboard and select Setup Guide from the drop down menu.
Press the start button next to the "Integrate using Web API or SMTP relay"
Follow the wizard steps to create your API key.
Follow the instructions provided rmisegal except provide a user name of apikey and use the apiKey from SendGrid as the password.

Not received emails even though the SendGrid activity shows Delivered

I have created Azure Logic App with Recurrence trigger and then used SendGrid connector for sending emails to multiple team members.
I didn’t receive any email even though the logic app actions executed successfully. After that I have checked SendGrid account email activity status, it is having “Delivered” status for the mentioned to email address in the SendGrid action.
Note: I have whitelisted the Outbound IP address of my logic app in SendGrid IP Address Management.
Twilio SendGrid developer evangelist here.
I don't know how Azure Logic Apps trigger emails with SendGrid, but if an email isn't being sent they shouldn't be getting the "Delivered" status.
You said that you have not set up Single Sender Verification or Domain Authentication. In order to send an email using SendGrid from the email address you provide, that email address should either have been verified as a Single Sender (which is mostly useful for testing) or it should be from a domain that you have authenticated with SendGrid.
Try setting one of those verification methods up and then try sending emails again.

Azure AD B2C Custom Policy Verification Email Customisation

I have set up a custom Password Reset policy in Azure AD B2C that allows the user to change their password while displaying custom branding elements depending on specific scenarios. This policy contains a step where the user verifies their Email Address by entering a verification code that is sent to their inbox.
From this post in the Microsoft Azure Feedback Forums: fully-customizable-verification-emails
It seems it is not possible to fully customise verification emails.
However, is it possible to perform some basic customisation of the verification e-mail within a custom policy? (text sent in the "From" and "Title" sections of the email and modifications to the text sent in the body).
Currently, you aren't able to customize the email messages, but -- as you have found on the feedback forum -- this is being considered by the product team.
You can customise the verification emails by using a 3rd party email service to send the emails.
For example, we have Azure AD B2C configured to send emails with SendGrid. We then use SendGrid templates to customise the contents of the email. This involves using Custom Policies, so it's definitely an advanced use case.
Once set up, you can create and use any SendGrid email template, and use the {{otp}} and {{email}} parameters in the body of the email, which will be replaced dynamically with the one-time password value and the user email address.
The instructions to send emails with SendGrid are here: https://learn.microsoft.com/en-us/azure/active-directory-b2c/custom-email-sendgrid?pivots=b2c-custom-policy
For Mailjet, the instructions are here: https://learn.microsoft.com/en-us/azure/active-directory-b2c/custom-email-mailjet?pivots=b2c-custom-policy

How to send email from delegated account using Gmail API

I have created an automated google script to send notification email on periodic basis but I want mail to be send from my delegated account since I logged in using my primary email, so I can't send it through my delegated email account.
I tried to achieve the same using send email as functionality but it is not working, recipients are receiving mails from my primary address.
Please provide your inputs
Thanks
First you need to add the delegated account in your usual inbox. Go to:
Settings>Accounts>Send mail as:>add another email address
Make sure that the "Treat as alias" checkbox is checked; submit and verify the request.
Second, you can access all the aliases with GmailApp.getAliases().
Finally, you are able to choose the alias with the Gmail Draft or Message Services by changing the from field in the option object.

GMail API - Can I send email using the Service Account?

When I send an email using the GMail API, I get an Access Token for the user to whom the message is to be sent and then when sending the message, I put some value in the From Field.
But no matter what I put in the from field, the message in the email shows as From "Me" and is in the Sent mails as well as Inbox.
Is there a way, I could use the Service Account to send the email, so that it does not show up as From "Me" and is also not in the Sent Mails.
You cannot use a service account to impersonate a free gmail account. I spent a lot of time confirming this after reading a reply that was here before. Maybe it worked at some point, but it doesn't anymore.
There is no way to share / grant another user permission to access
your standard gmail account. So there is no way for you go delegate
the permissions for bob#mycompany.com to access bob#gmail.com.
and
you can impersonate G-Suite accounts but not Gmail accounts
These quotes are from Google's official C# Auth repo:
https://github.com/googleapis/google-api-dotnet-client/issues/1561
No. The Gmail API is for Gmail users and service accounts are just for doing auth to a real Gmail account, they don't have their own Gmail account, etc.
If you want to send the email from some service, you need some bulk-sending email service like at: https://cloud.google.com/compute/docs/tutorials/sending-mail/ or something you run yourself or from some other provider.
No, what you are looking for is a bulk email sending service. Checkout sendgrid , Amazon AWS SES, mandrill or if you want to stick with Google, this. You could of course run your own postfix server (although I'm assuming you were using gmail api for deliverability in the first place.

How can my appengine app send mail using the senderid of domain that installed the app

Say I have an appengine app called foo at foo.appspot.com and my email i.e. adminfoo(at)gmail.com is it's adminstrator.
Now, I want to sell this service to blah.com. blah.com has a google app account and 'adds' the foo application and sets the url http://foo.blah.com to point to it.
Now, using the new namespace manager, I carve out separate data for blah.com but when blah.com wants to send out email currently the only way it is possible is either
sender is admin i.e. adminfoo (at) gmail.com
or foo.appspot.com has to add someone(#)blah.com as a developer
Is there any other way? What happens if one has 1,000's of customers ?
Also, the docs state that the email sender can be 'the currently logged in user'. So, if someone(at)blah.com were to 'login' using the google login and 'stay logged in to the app' than can the app send email on behalf of someone(at)blah.com with someone(at)blah.com being the sender?
The other way is that your app can send email as anything#appid.appspotmail.com, where 'appid' is its App ID. As you say, you can also send email as the logged in user - but only on requests made by that user - so sending mail as them from the Task Queue is out.
You might want to look into an 3rd party E-Mail provider. We use http://postmarkapp.com/ for our AppEngine projets (via huTools.postmark) and we love it.
