hello,
this is off-topic but urgent.
i need to send 70.000 emails in an hour. i dont know which smtp service fits me and how to find it.

can someone help me with information please

thanks a lot

At work we use FuseMail.com for outbound mail relay, have no idea on pricing though or if they'd even go to 70,000 mails an hour.

Is this a one-off mail? Why do they all have to go within an hour?

You are VERY likely to be rate-limited or blocked from many mail services if you try and send a large number of mails in to their system within such a tight timespan.

Please read the "How to ask a smart question" link in my posting signature, and the LQ Rules. This is NOT urgent for anyone here...we are all volunteers.
Good luck getting help with this. 70,000 emails an hour sounds VERY much like a spammer...so why would ANYONE volunteer to help a someone shovel out junk email?? Can you tell us ANYTHING about what these emails are going to be? Why? Details??? Is your company bonded, and has it worked with the various big providers (Yahoo, Google, AOL, etc.), to get added to whitelists as NOT a spammer??

Also, no matter what you set up, good luck finding an ISP that will let you shovel out that volume, without immediately blacklisting you. There are many bulk email services that you can find. PowerMTA is a decent solution, but if you are running a LEGITIMATE business, and need such volume, outsource it...there are companies that do ONLY bulk emailing.

I should have mentioned that we use FuseMail.com and regularly (at least once a month) have legitimate mail-runs that would be 20,000+ e-mails and it does take a bit of co-ordination with various partners to allow us to process this volume.

Indeed...but 70,000 AN HOUR sounds a bit suspicious. Outsourcing big email runs is probably the best way to go for a legitimate business, which is what you're doing.

While it certainly does sound suspicious, the reputable companies that supply this kind of service (mailchimp, sendgrid, etc.) will probably take at least some care to make sure the mail being sent is legitimate.

How do something like big cities or towns send bulk emails to parents like when school is canceled? I mean 4 or 5 of us get emails because the kids subscribe, I get them, my wife gets them.... And then there's the other 20,000 families in town. Probably a lot like spam activity, but not.

Agreed, and they probably do. The reputable bulk emailers are good to deal with, and if you have a legitimate business, you probably won't have problems.
I think (?) some of it depends on the domain...a .edu or .gov may be exempt from certain restrictions like that, and they probably also use a bulk-mailing service to make life simple. And even if you have to shovel out 100,000 emails from your own mail server, you're probably not going to do that in an hour. And, since blacklists can be constructed from users reporting mail as spam, the "a2802_18@yahoo.com" address will be flagged, while the "cancellations@school.edu" won't be (at least by the user).

The mass message service providers work very hard to be can-spam compliant and pester (I mean remind) parents to white list the email sender, but those school emails get marked as spam pretty regularly too. Most providers throttle email, but depending upon what your list looks like the throttling may or may not affect what you are doing. If your list is clean and spread across email domains throttling might not be an issue. If your email list is 80% yahoo addresses or whatever then a service might balk.
