How to configure a Sendgrid SMTP account for GMass

If you’re using the GMass unlimited sending option by connecting an SMTP service to GMass, you may have chosen Sendgrid as your SMTP service provider. If so, here is how you we recommend that you configure your Sendgrid account.

  1. On April 6, 2020, SendGrid changed its requirements for new accounts. Accounts created after this date are required to verify individual sender addresses or a sender domain. More information on SendGrid’s website here: https://sendgrid.com/docs/for-developers/sending-email/sender-identity/. If you created your SendGrid account after April 6, then the easiest way to proceed is to verify the “from” address that you’ll send campaigns from in your Gmail account. That way you can avoid complex DNS entries and your emails will still be SPF and DKIM compliant. As soon as you log in to your SendGrid account, you’ll be directed to verify a sender, so proceed with that before the rest of this setup. If your SendGrid account was created before April 6, 2020, then you can skip ahead to step 2.
  2. GMass will connect without TLS/SSL to the SMTP server on the port of your choice. Sendgrid allows you to connect on ports 25 or 587. As of October 2020, you must authenticate into the Sendgrid SMTP relay with the username “apikey” (this is the same for everyone) and then your actual API key that you create from inside the SendGrid interface. Note that you cannot use the username/password that you use to log in to the SendGrid website. See below for an example. Remember: the SMTP username is always “apikey.” The SMTP server is smtp.sendgrid.net.

    This is how you will set the Sendgrid server to be used in GMass.

    set Sendgrid SMTP server
    Configure your GMass account to send with Sendgrid. You must set the username and password to be “apikey” and your actual API key. Do not enter the username/password you use to log in to SendGrid.

  3. Ensure that open and click tracking are turned OFF. This is because GMass will add the tracking for you if you check the box for open and click tracking under Settings, and we don’t want the emails to be double tracked. Here is how the “Tracking” section of Sendgrid should look:
    Sendgrid Tracking
  4. Ensure that Bounce Notifications are on. Set them to go to the From Address. This will allow GMass to process your bounces, just like normal. Not all SMTP services have this capability. Sendgrid and JangoSMTP do. Mailgun and Mailjet do not. Therefore this is what your Mail Settings screen in Sendgrid should look like:
  5. We generally recommend users do NOT get a dedicated IP address with Sendgrid. We’ve spoken to high level staff at Sendgrid who have explained that dedicated IPs start off as cold IP addresses with no sending reputation. That means that initially, with a dedicated IP you’re likely to see more deliverability issues than if you use an IP address from Sendgrid’s shared pool. Here’s an article explaining the pitfalls of dedicated IPs. The only exception to this rule is if you plan to warm up your IPs over time by sending low-volume emails in the beginning and then ramping up.
    Sendgrid Dedicated IP Addresses
    We recommend that you do not get a dedicated IP with Sendgrid.

     

  6. Similarly, we recommend that you do NOT whitelabel your domain either. Sendgrid highlights the deliverability advantages of a whitelisted domain, but because they force you to create a sub-domain of your domain, and don’t let you use your actual domain for the sending and signing of emails, your sub-domain will start off with no reputation and will likely cause delivery issues. Note: Some Sendgrid accounts require you to whitelabel your domain. Here’s how to get around that.

    Since our beta launch a few weeks ago, several users who set up a domain whitelabel have had spam and deliverability issues, specifically where Gmail highlights the white-labeled sub-domain as the source of the spam problem.

    Sendgrid Domain Whitelabel
    We recommend that you do NOT set up a domain whitelabel in your Sendgrid account.

     

  7. Lastly, do not set up an white-label email link either. This is equivalent to the branded tracking domain feature of GMass. Since we previously turned OFF Sendgrid’s open and click tracking in to avoid double-tracking, there’s no need to customize email links with Sendgrid.

    Sendgrid Link Whitelabel
    Setting up link whitelabels is irrelevant because you should have turned OFF open and click tracking in Sendgrid, since this will be handled by GMass.

    1. You aren’t sending it to us, you’re setting it to your GMass account. When you press the GMass button to “set” the SMTP server, you are saving that access info into the GMass system so that GMass is configured with your SendGrid account and can route through that server. It is safe to do.

  5. You are asking us not to enable a domain and email whitelabel, but sendgrid ha put a restriction of 100 mails/ per day if we don’t add it. What should be done now? I have been using sendgrid to send mails from GMass for mails less than 100 so far.

  17. It seems that Sendgrid can’t integrate directly with Gsuite (according to Sendgrid’s and Gsuite’s support). How are you guys able to integrate the two?

    Reply

    1. Hi Eric,

      SendGrid and G Suite currently do not have integrations directly with each other. Since GMass integrates with both, it becomes the link between the two services (SendGrid/G Suite).

      If you have your SendGrid account connected to your GMass subscription and is active on your G Suite/Gmail subscription, you’ll be able to compose your emails through Gmail and send them through SendGrid via GMass.

    1. Hi Faith,

      Reasons that an email platform filter your emails as spam varies from one platform to another. The best way to check what the reason is provided is to test sending to a Gmail account of your own. If the email ends up in spam, see if a reason is provided, like in the example below:

    1. Hi Roy,

      You can select to send your campaigns either via Gmail/G Suite servers or through SMTP. Your limits on either option are independent of each other so if you opt to send via SMTP, your daily sending limit in Gmail is untouched until you send another campaign through Gmail.

    1. Hi Nicole,

      Upon checking, you used GMass to send a campaign to 267 recipients which GMass has already done. Please contact our support team (gmass.co/g/support) as we would need for you to send us screenshots of your reviews in order for us to differentiate which reviews are yours since Google sometimes changes the user name to “A Google User” due to account privacy settings.

  37. Hi there – I successfully set up Sendgrid, but when recipients receive emails sent via Sendgrid the email has “via Sendgrid.net” next to my email address. This makes the emails seem more suspicious to my users.

    Is there a way around this? Sendgrid recommends Domain Whitelabeling (now called Domain Authentication), but GMass specifically recommends against that. Any assistance would be much appreciated.

    Reply

    1. Hi Emon,

      If you want to avoid the “via sendgrid.net”, you can use Sendgrid’s “whitelabel domain” option. That will make your Return-Path based on your domain instead of Sendgrid’s. Just make sure you then adjust your SPF record per Sendgrid’s settings. Please note that since they force you to create a sub-domain of your domain, and don’t let you use your actual domain for the sending and signing of emails, your sub-domain will start off with no reputation and could cause delivery issues.

      Reply

  38. Hi there – I’d like to remove the “via Sendgrid.net” that recipients see when I use Sendgrid. According to Sendgrid, this requires Domain Authentication (Domain Whitelisting). As this article specifically recommends against domain whitelisting, I wanted to see if you had another approach to removing the “via Sendgrid.net”.

    Thank you!

    Reply

    1. Hi Chris,

      After logging into your Sendgrid account, click on “Setup Guide” on the left navigation menu by clicking your account name which would bring down a dropdown menu.

      You’ll then be presented with the action you want to take, select Integrate then choose the option to “Integrate using our Web API or SMTP relay”. Click “Start”.

      Under SMTP Relay – click on Choose.

      This will bring you up on a new page where you’ll just have to name your API Key, click on “Create Key” which will generate an API Key for you. Take note of the details that will populate near the bottom of that page after clicking on “Create Key” as this is the details you would need to set your SMTP settings (https://www.gmass.co/blog/smtp-server-send-unlimited-emails-with-gmail-and-gmass/#attachment_1832) to your GMass account.

I’m not seeing the “use the from address” check box in SendGrid’s “Forward Bounce Messages” section under “Mail Settings.” I added the domain that I use to send emails from out of my G Suite account, but any bounces that I get come through from SendGrid and don’t appear to be getting processed by GMass.

    What is the proper “from address” to use to allow GMass to process bounces?

    1. Hi Jose,

      The SMTP test lines are automatically populated when clicking the links at for each service provider. So if you’re using Sendgrid, you would just need to click the Sendgrid link below the first text field. Use APIKEY as the username, and the actual API Key from your Sendgrid account as the password.

      In the TO and FROM address, indicate where you want to send test email and from which address you’re sending from.

      GMass allows you to artificially break the Google-imposed and enforced sending limit by breaking down your campaign sending over multiple days. It also has features that are not available by default in GMail, such as individual mail merge capabilities, open and click tracking, and auto follow-ups among others.

  51. Hi, I’ve setup everything mentioned in this page.

    However – my sendgrid account is currently Free for 100 emails/day

    So – In the billing section – I already inserted my Creditcard details.
    Now I am trying to upgrade to the paid plan (Essentials 40K)
    But this option is grayed out. It’s not allowing me to select it.

    At the top of the page there is a message:
    “Finish your account setup in order to select a paid plan and unlock the full potential of Twilio SendGrid”

    But – in order to finish the setup it seems that domain authentication is mandatory.
    (“Authenticate your sending domain”)

    So – in the article above point #6 – GMASS is saying:
    “Similarly, we recommend that you do NOT whitelabel your domain”

    But on the otherhand – it seems that Sendgrid requires Domain authentication (which is my understandin the same as whitelabel)

    Now – If this is mandatory – but GMASS is not recommending it… What shoule I do?

    If I understand correctly then authenticating the domain will also require me to start messing around with SPF, DKIM, and DMARC 🙁

    Will appreciate your help!
    Thanks,
