IT gurus, saidia

I have like 28,000 email on an excel sheet, which is the best tool that i can use to send a mass mail effectively.
Most of the wordpress plugins that i have tried seems not able to send this huge number.

Also on the SMS part for like 2000 contacts.


@amun leta code

For sms use smsleopard. They actually allow you to send customized sms straight from your excel sheet. The kinds of “Dear [Name]”

refactor to match your requirements cc @Mkulima , and happy coding

Your tool haina queuing capabilities?

Hii itawekwa wapi kwa wordpress? She hasn’t told us if she’s sending from her website or a desktop mail client…

even if from a website, just create a library that inherits from IHttpHandler

:D:D:D I doubt the host has .NET


has native support for PHP which in turn supports .NET since PHP 4

Right. But rarely used… because most PHP sites are hosted on a Linux distro. And in case you want to deploy ASP.NET scripts then you’ll generally have to host on a Windows Server.

i understand what you mean :D:D:D

but you can still do mono

If you have a VM of your own. But on a shared hosting… utaambiwa wacha kusumbua.

you dont need tech support to run mono on apache, sometimes its good to tryout this things

but the i agree with you, for the faint hearted, they are better just using phpmailer

I would have suggested a 3rd party mailing service that has support for queing and all that. 20,000 mails at a go na maybe site iko Kenyaweb ataangusha server ya yenyewe.

Ama awekewe cron job that can send the mails in the background pole pole.

never been a big fan of third party libraries, unless i triple check every single line of code :D:D:D:D

You subscribe to the “Not Invented Here” school of thought

been there, seen it all, i hate the easy way out, once re-compiled some open source piece of shit, 3 weeks later all my alarms went off ,DOS attack, since then… never ever

Thought @amun ni dereva wa trela…wueh!

tumia mail merging

Lipia MailChimp .
