Google Workspace SMTP Relay Quota

[PJStalls]

Hi,

We moved to Google Workspace a couple of days ago after having self hosted emails on a previous setup via WHM/cPanel, but it's been a right nightmare since.

Have
- Set up SMTP relay settings and followed Googles documentation (sending emails are not a problem via IPB, it's just a quota issue)
- Set up SFP and DKIM in case that would help 
- Cancelled the trial period as it was suggested as an option to increase limits
- Pre-payed for a month (3 licenses) as that also was suggested as an option to increase trial limits

We're not sending out any type of bulk mail. The only mails being sent out are user registration, password reset, digest, etc. When looking through different help documents online, I keep seeing 10 000 being mentioned as limits, but we're getting error messages (see below) after sending somewhere among the lines of 150-200 emails (according to the email statistics page, we need to send around 250-300 a day unless it's possible to cut down system emails like "Your registration is complete!" and otherwise, but it would seem like a drastic move)

Does anyone have any tips (or know what the quotas are) on how to get this resolved?

Limits per user

• The maximum number of messages a user can send in a 24-hour period is 10,000. However, this can vary, depending on the number of user licenses in your Google Workspace account.
• A registered Google Workspace user can't relay messages to more than 10,000 unique recipients in a 24-hour period.

Yeah, that's also the numbers I've been seeing, but we are incapable of sending more than literally a couple of hundred emails before getting blocked for a day.

How many user licenses do you have in your Google Workspace account?

[PJStalls]

Hi Nathan! We have three licenses, where the third one is only used by the forums.

Limits per customer

These limits are determined by the number of user licenses in your Google Workspaceaccount. For small customers, these limits come into effect much earlier than the limits per user.

There are two per-customer limits:

• The maximum number of total recipients allowed per customer per 24-hour period is approximately 130 times the number of user licenses in your Google Workspace account, with an upper bound of 4,600,000 recipients per 24-hour period for large customers. If a customer exceeds this limit, users see the error "550 5.7.1 Daily SMTP relay limit exceeded for customer."
• The maximum number of total recipients allowed per customer in a 10-minute window is approximately 9 times the number of user licenses in your Google Workspace account, with an upper bound of 319,444 recipients per 10-minute window for large customers. If a customer exceeds this limit, users see the error "450 4.2.1 Peak SMTP relay limit exceeded for customer."

You should be reading the "Limits per customer" section - highlighted the important bits.

Holy ... Not sure how I managed to miss that one. Had gone back and forward reading through stuff and every link kept dangling the 10 000 limit.

Oh well. Would it be possible to get i.e Amazon SES and only use it as a SMTP relay and keep MX at google? And then add Amazon SES IP to SPF (not sure about DKIM)? 

Anyone knows if it's reliable or is it troublesome IP-reputation wise using SES? I tried to set up a cheap server with WHM/cPanel on digitalocean just to try to send some of the forum emails via self hosted, but all the larger email providers sent back a big "nope" saying ASN was blocked and whatnot.

If anyone has any pointers or tips for services how to get this sorted, it'll be greatly appreciated 😃

Yes. We do this.

Subdomain points to send grid, and aliases in Google that redirect email from address@example.com to address@sendgridsubdomain.example.com.
