Attachment limit size by official Postal Service like "Postmark" - sendgrid

I have connected my react app with my Postmark server to receive webhooks, but attachment limit size is only 10MB, in my case I would need more than that, at least around 20MB or bigger.
Does anyone know which platform can provide me this?

Email and image url - how to prevent image blocking by email clients

From my application I'm sending email but email client (for example Mozilla Thunderbird) blocks the images. I use image urls from my website.
Is any way to prevent the image blocking by email clients ?
No. How do you expect to force a 3rd party application to download data it doesn't want to download? All you could do is make your email unreadable without downloading the images, which will increase the likelihood of both being treated as spam and of being deleted unread.

Does Mandrill have a limit on Email size or POST size through API?

The scenario: HTML emails are getting delivered successfully through Mandrill but the content looks as though it's cut off half-way through the email. Mandrill is giving me a JSON success message when I hit the API using POST method.
Because the HTML is cut-off halfway through the email it makes me think there is either a character limit for the email Body/Message when POSTing or there is a limit in Mandrill on the Body/Message size of the email.
My question is; is there any known limit on either POSTing to the Mandrill API or on the Email size sent through Mandrill? Or any other suspected reason for this happening?
(The account Mandrill is in test mode at the moment, I am also using FileMaker's [Insert from URL] method to POST - in case this information is relevant.)
From Mandrill Knowledge Base:
Messages in Mandrill can't exceed 25MB in total size (including
content and attachments). There is no specific limit for individual
attachments, just the total size of the message. Because attachments
are Base64-encoded, this generally means that they will be 1/3 larger
when sending than they are on disk due to the encoding.

Gmail blocking pixel tracking / 1x1 pixel since today morning

I was implementing pixel tracking for a gmail web service, but since today google has changed the gmail client to proxy linked images !
Is there any work around, as the proxy is giving my server a fake/masked ip and location?
This is true. gmail has been proxying all user content via it thus showing Mountain View,CA as its REMOTE_ADDR. This is true only for gmail clients. The same logic has not been working on Gmail via outlook or any other mail client.
Most email tracking companies rely on these details to differentiate the recepients of the mail.
I dont think there is a work around. But if there is one we would find out soon given that these companies have a lot to lose.
Meanwhile, you could try using HTTP_X_FORWARDED_FOR or disposition notification headers. But given that this can be messed with, there isnt much option left but just go back to making people click on links!!!
In my experience as of Aug 5 2018 my emails sent with a tracking pixel are blocked by google. I uncheck the send tracking pixel box in my crm and the message arrives instantly. The tracked email never arrives.
I made a video to show but its exactly as I just described and quite boring to watch lol. BUt you get the point. Obviously this is just in my experience but it's too bad because knowing if my clients read it is only way know not to keep sending the same message in a different way assuming it went to spam.
Looks to me like they're caching, not just proxying.. I whipped up a PHP file to output a random image selected out of a collection of 5 images... It's the same image each time.. Testing against Yahoo! mail and outlook, both of which change each time the email is opened..

reliable delivery service - email, sms

I am looking at building an ordering service, this is fine but my question is how to reliably get the order to the shop. It is a fast food shop.
Are there any solid delivery options either via sms/phone or an email service that is pretty much 100% reliable.
Take a look at some of the SMS providers like Twilio who give you web based APIs for sending SMS messages. There is also an API called the OneAPI that is currently available in Canada but will be in other regions soon. You can use this to send SMS messages through a html API.
For email, take a look at some of the providers listed by programmable web, there are a bunch, for example Yahoo lets you send messages via their API.
Yes make sure call back to sender for confirmation,...
check on my DMStar CBuilder6 system.
it fetch filtered email and sms QFree ordering system.
Every minute or so will auto print out onto docket dot matrix printer as soon order received.

unable to deliver a pdf attachment to clients

On our website which is asp.net, we make a sale and an automated email is sent out to the client with an attached PDF invoice we create using a 3rd party app. We are having trouble getting these delivered successfully to some corporate clients. Yet we also send a copy of that same email to ourselves which we receive fine. We can then forward this on to the client and they do receive it no problems. So the original is not received but the forwarded mail is.
The webserver is a seperate IP address to our office Exchange server which sends the forwarded mail.
I have tried to find the difference between the 2 mails and it looked like a rich text issue, except that the mail is plain text or html!
The question is a little vague i know as i do not know where to look for the best. It seems to make no differenec which mail program is used, we tried MailEable and it was the same thing.
Mail is logged on the web server as leaving and that is the last we see of it. It doesnt bounce but it is definatley delivered to the client server, but doesnt reach the recipient. We used to track thru Message Labs and it would say it had reached the destination server ok. We do not use ML anymore until we find the issue, keeping it simple.
We have no issues sending to AOL, Hotmail and Yahoo etc.
It appears something in the email is upsetting server based spam software.
We havnt been able to get hold of any email logs from clients.
any suggestions?
Check out this link mentioning a reason not related to size issues
The SMTP (internet mail protocol) RFC (An RFC is a document describing
the standards that make the Internet work.) explicitly states that the
length of a single unterminated line can be 1000 bytes, no larger.
Some SMTP servers violate this, and the Firebox (this is our firewall)
will drop the connection when the line length exceeds the configured
length, which defaults to 1000.
which might indicate your pdf generator and/or mail generator creates output that's not 100% standards compliant. Might be a good point to check as it could explain why certain customer suffer fom this problem only.
552 Requested mail action aborted: exceeded storage allocation
This means there was a violation at the client's ("customer's") mail server. The message exceeded a threshold/limit of some kind. It's not clear if this is a per-message limit or if the user's mailbox is just so full that it cannot accept another message.
Either way, this is mostly out of your control. Only thing you can do it try to keep your e-mail messages and attachments as small as possible. If you can, compress (zip) any attachments before sending.
