Email Testing Services?

Question

Software testing

I'm a little stuck with testing email campaigns, please help.
Advise services for testing.

Basic requirements:
- viewing from various devices (mobile) and various mailboxes (gmail, Outlook, Yahoo, that's all)

It would be nice, but not so important:
- checking the "reputation" of the sender (me)
- blacklists
- A/ B
- and all that

P.S.
Yes. Google broke, banned and all that. I've already shoveled a bunch, asking for maps, numbers and other links, without even letting me look at the dashboard. Reviews are very biased and are more promotional than practical.

Answer 1

To check a message in terms of spam filters:
spamtest.smtp.bz

To check for spam the word
spamtester.bazaaremail.com
To check the reputation of a domain and deliverability of letters
If sending via RuNet
postmaster.mail.ru
postoffice.yandex .ru
postmaster.google.com
If sending across Europe and the USA, the main postmaster is Google Microsoft
has something similar https://sendersupport.olc.protection.outlook.com/pm/ iCloud postmaster.icloud.com Mail Com - postmaster .mail.com but they don't provide such information A similar postmaster is created on AOL and Yahoo https://postmaster.verizonmedia.com/,
but I haven’t dealt with it yet, I’m waiting for the end of beta testing.
Still the best mail ru postmaster, who sees every letter and presents everything very clearly
Yes, and you can get some information by setting up DMARC correctly

There is no viewing from different devices and mailboxes, but a complete picture of setting up a smtp server, spam asassin and reputation.

Answer 3
