Emails to gmails aliases randomly not delivered using SendGrid

Twice a day I send emails to multiple aliases connected to my google account. Let's say I send emails to 8 aliases - every time only 3-5 recipients (also random recipients)got emails in their inbox - the rest is missing. I checked spam, bin and filtered folders as Google recommended but ran out of ideas for now.
Also SendGrid UI says that all emails were "DELIVERED" and I use dedicated IP for delivering emails - SenderScore shows my reputation is uknown - maybe I send too few mails a day?

How does third party send bulk emails from gmail?

Gmail has a 24 hour rolling period limit of 2000 emails, outlook has a limit of 1000 emails and all other service providers has a limit.
How does Saleshandy and sendpluse send almost 10k emails per day from gmail when the limit exists? What should I do if I want to send such number of emails? Is it possible using python?
Gmail and outlook both do indeed have certain restrictions and limits when it comes to the number of emails that can be sent out in a day; unfortunate I know.
I am Vatsal from SalesHandy, and I will explain the process of sending 10,000 emails from Gmail (& outlook) all at once.
SalesHandy’s mass mailing feature with automated follow-up lets you schedule as many emails as possible and yes, we are talking more than 10,000 emails too.
We mentioned that you can schedule all of these emails to be sent at once, but the sending will be limited by your email service provider's daily email sending limit. It is not recommended to email blasts at once because it may harm your email account's reputation and cause your emails to end up in the recipient's spam box.
Mail Merge Campaigns can be sent using SalesHandy.
If you wish to know more on how exactly one goes about this process, you can read our detailed blog here - Gmail / Outlook.
Feel free to ask me any other questions you have! :)

Google Drive Daily Email Limit?

We have a few Google Forms as part of my work. I am using the Form Emailer script so that, when someone fills out the quiz, that person and also a person here in our office will receive an e-mail displaying a summary of their responses.
We just had a meeting and so many more people are filling them out right now. My question is, what is the daily e-mail limit when sending in this way, a custom form script?
Keeping in mind that two e-mails are being sent with each form completion, one to our person and one to the person that filled it out.
I tried to research this but I am getting conflicting information--some sites list the limit using Gmail, for example, but I don't think this is the same thing?
Any help is appreciated, thanks!
The limit will depend on the account type that is sending the emails. Since you are sending a message to a respondent (1) and a monitor (1), each of your mails will count as 2 recipients.
Your daily limit will be 100 or 1500 per day.
A script can test your remaining limit by calling MailApp.getRemainingDailyQuota().
Ref Quota Limits tab.

Reduce time spent sending emails from days to hours

A client sends out monthly emails to about 1 million users which will grow with time. They currently send through an in-house exchange server.
Their current approach starts with first preparing all emails, recipients and attachments, then a script starts feeding the exchange server. Sending just a million mails generally takes days.
My role is to propose a better approach/solution that can get these emails sent and possibly delivered within hours. The choice of using 3rd party services like amazon ses and sendgrid exists but what will make the delivery time reduce as required.
I'll start this with two disclaimers: 1) I am a SendGrid employee, 2) This question is right on the border of questions StackOverflow doesn't like.
That said, both SES or SendGrid will be able to process emails at a rate much faster than 1 million over several days.
Speaking for SendGrid, we accept all mail passed to us and queue it on our end, so if you're able to send a million emails at us in a second, we'll accept them and deal with queueing on our servers. So that answers the question of how fast you can get the mail away from you; leaving the question of how fast it will get to your users.
That's a harder question and depends on a number of factors, including if we're receiving negative feedback from email providers (Google, Yahoo, Comcast, etc.), and your typical send volume. All said, it could take anywhere from a few minutes to a few hours, but days is definitely unheard of.
As far as I know SES will do something of the same nature. SES enforces client side send rates (meaning you'll need to send them only N emails per period), but this can be upped greatly depending on your volume and trust. Again, as far as I know, SES should take anywhere in the neighborhood of minutes to hours to process and send 1m emails.

What is the best email frequency for high volume transactional emailing?

Let's say we send about 100k emails per day to our users.
These are all transactional emails ("You received a new message",etc.)
In order to reduce the number of emails we group those transactions into summary emails and send those summary emails every 6 hours or so.
So every 6 hours or so we send about 25k emails.
From particularly hotmail's perspective is it a bad practice to send all these emails every six hours.
Would it be better to send these emails every hour for instance?
Thanks,
Haluk
The best way to send - is to send uniformly. Every hour is better then every 6 hours. Every minute is better. Think how mail services like gmail work. They send and receive mail every minute. If you'll send a large chank of mail at a short time and then will do a delay - that will look more like spam.
