Get forbidden to send email with multiple recipients - sendgrid

I am facing a problem that when i send to multiple recipients (about 100), it response forbidden. But it was fine previously. And I have tested to send few recipients (about 3), it works fine.
May i know is that any change on free plan?
Many Thanks for the help.

The free Sendgrid plan allows you to send up to 100 emails a day. If you are trying to send more than that 100th email in a day then you won't be able to and you should upgrade to a plan that supports more emails.

Sendgrid sending email but many are being deferred: status code 202

We are using sendgrid to send a weekly newsletter to about 50k emails. We have an authenticated domain as well as two of our own IP addresses. Our script batch sends 500 emails at a time to all the addresses with personalization. However, when we run the script, many of the emails are being processed and then being deferred according to sendgrid logs. The response is 202. Some emails receive the newsletter but others do not. Any suggestion on how to resolve this issue?

I would certainly follow flaxon's advice, check the dashboard and see what it says about your delivery as well as bounces or spam reports. There is a good article here on what being "deferred" means too.
I would also look into SendGrid's Marketing Campaigns. It is a better way to send bulk email, like to your 50k email list, than making several requests as you describe.

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! :)

Cleaning up email distribution list of bad/invalid emails

We have a newsletter where people opt-in (everything is on the up and up here). As people leave jobs (fired, layoffs, etc.), we still send to those emails and now after a few years, we have a considerable amount of emails that need to be purged.
The inbox that is receiving the bounces/invalid emails is a gmail account. We can filter (via a search) and find the emails that need to be removed but how can we export those emails to a list so that we can clean up our distribution list? Are there any tools that would help simply this?
We are looking into mailgun and sendgrid for future send outs but we need to clean up the list before we migrate. Any help or suggestions would be appreciated.
Our tech stack is apache/coldfusion 11 (not that it matters but in case it helps).
You could use CF to log into gmail and pull all the messages. Then loop through them all to find the bounce messages. Appending those bounced email addressed to a simple flat file. If you want to get fancy you can use a database, but I think a simple text file would do in this case. One email address per line.
I just read that you are deleting those bounced email addresses from a database. IF you're confident of your coding the above idea, you could directly delete from your database rather than saving a file.

DirectAdmin Blocks after 100 non-existing emails

I have installed phplist on the server for E-mail marketing but when it has send 100 E-mails to non-existing adresses DirectAdmin blocks the email account.
When this happends I must change the password but I have a list of 30.000 E-mails which needs to bounce first so I know which E-mails to delete from the database.
Is there a way to avoid the blocking and keep on sending E-mails to non-existing adresses?
I think you have setup mail limit on your server and due to that you are facing this issues, Please check following direct-admin help docs and try to update your mail limit.

Create a lot of 200 different Email Accounts in a short span of time?

I am trying to send bulk email from a few accounts email accounts, and for some reason, I think the emails get blocked and they do not reach the recipient. I think it is because of spam / filtering rules. Is it possible for me to create say 100 different email accounts in a very short amount of time and send 1 email from each of the accounts ?
Is there any service/ idea / script to create a lot of email accounts in a very short amount of time ?
Creating 100+ accounts on your own server would be pointless. It's usually the originating server and isp and/or the email's content that causes it to be flagged as spam. Creating 100+ accounts elsewhere MAY work, but then each of those other servers may also be considered as a spam source and any mails you send from that particular account will go missing as well.
You can check your mail server's logs to see if the mails get dumped by the receiving mail server. Some of them will do the filtering right at the initial connection/send attempt. However, some will pretent to accept the mail (and you see a 200 OK acceptance message), but then toss the mail in the trash automatically. In this case, you'd nave no idea what happened, as everything would appear to have worked fine.
I had set it up easily using Yahoo Mail Plus. They had the feature of Disposable Email Accounts. You can create 500 of them !
