In order to operate the forum, it is necessary to have an SMTP service, which can be either paid or free. The number of daily emails sent, such as registration confirmations and notifications, is quite limited, not exceeding 5000 in my opinion.
I would suggest trying out Mailgun (https://www.mailgun.com/) as a service provider. They offer a free trial allowing you to send up to 5000 emails within the first month, after which they will require payment for continued use.
Based on my understanding, they offer standard levels of service, and even promise an SLA (service level agreement), which is reassuring. One thing worth considering is whether 5000 emails per day are needed, as the free trial may not be sufficient for high volume email senders.
It's always wise to research and compare various email service providers before making a final decision, as each service has its unique features and limitations.
Amazon SES is a quite economical email service. Sending from almost any application. Setup is fast, supports: sending transactions, marketing emails, mass mailings.
Email authentication capability, sender reputation protection.
SPF, DKIM, all these are there. Full GDPR compliance, which is important.
The analytics were pretty good, too.
Try it. (https://aws.amazon.com/ses/?nc1=h_lsnc1=h_ls)
It is strange that this question is raised, although probably not everyone knows that there are many SMTP services that do not charge a cent for their services (of course there are restrictions), as well as many quality services with a minimum payment.
One of them is Google SMTP. There is a limit in letters - 5000 for 24 hours. Amazon also has a free feature - 64000 (then $0.10 for 1k emails).
Of the paid ones, I would single out Moosend ($9) and Mailchimp ($20 for every 500k emails per month).

Used mailgan for several years, no questions about reliability/deliverability. There were downtime (allegedly lying under DDoS), but not critical - a day or two in 3-4 years.
What bothers me is their Soft/Hard Bounce, subsequent blocking and imposing e-mail validation service. The problem is that it is impossible to validate mailboxes on some European mail services - all requests for existence get a positive response, even if the box really does not exist. And since I have them accumulated a total of about 40%, and the rejection rate is very high, respectively, exceeding the "rebound" and blocking. Unblocking only by letter within a few days.
As a result, for European users do not advise.

You're not quite right.
Google Workspace has limitations for the free version. And they don't meet the desired criteria (5000 posts
per day) set by the topicstarter.
You can read more about the restrictions that apply to the free and paid versions of Google Workspace at: link (https://support.google.com/a/answer/166852?hl=en)
It should be noted that Google Workspace will need to be worked with via API.
Create a project in the Google Cloud Console, activate the application in it, and play with the settings. It's long and complicated.

Sending via ordinary SMTP Gmail to a simple user with OAuth authorization, even if there were no limitations, would be very harmful. Both in terms of possible crashes and security.
But there are restrictions, and they are unacceptable.
sendgrid / elasticemails / sendpulse all have free plans.
The free rate from SMTP.bz is great for you
Try it for a month or two. Will 15000 emails be enough for you?
There is, however, a limit on sending per hour. They allow up to 50 mails.
I don't think you will get to 5000 letters at once.
If you don't have enough you can subscribe to a different plan. The prices (https://smtp.bz/price) are all right.
Is there a way to verify the accessibility of an external SMTP server, such as Google's aspmx.l.google.com, and if so, how can this be done? I attempted to use the net.tcp.service[smtp,aspmx.l.google.com] method, but it returned 0 indicating that it did not reach the server or receive a response.
On the other hand, using Putty, the connection from my computer to the server works fine. Furthermore, the net.tcp.service[smtp] function successfully connects to the SMTP server registered in the Zabbix settings (Configuration -> Services -> Email), and receives a response.
However, when attempting to ping any external server from our server, it fails. Is using an external check, such as a separate script, the only possible solution to this problem?
It is important to investigate any connectivity issues thoroughly and explore all possible solutions when working with SMTP servers. I suggest consulting with a network administrator or researching online forums for similar issues and their resolutions.
