I want to send group opt-in emails to promote my offers,so what is the process of sending 5k eamils per day? thanks
Sending mass emails is not difficult. Fist off you'll need a good email client. You'll also need to buy an appropriate to your needs number of smtp relays (to bypass ISP restrictions on your outbound email messages). Once you have these things set be sure you deliver your subscribers quality information (news, promos, discounts), don't just say something like "buy my services". Don't send emails without unsubscribe link in it.
Getresponse.com is a great website for scheduling and sending emails. You can set up emails going out at a rate of your choice over days, months, however you want to set it up. Hope this helps.
MailChimp has free plans and is also cheap when compared to aweber or getresponse. If you have a powerful VPS hosting, you can buy/install email marketing scripts on your VPS. Get some additional IPs and do the mail marketing to the list of people you opted in for your mails.
One method is to use Yahoo Groups. You can subscribe into multiple relevant groups and there u start sending mails regularly. Keep those mails interesting, informative and compelling to read. You can slip in some offer mails in between ;-) This worked for me 3-4 years back. But haven't tried these days, but must be still effective.
It is very much difficult to send 5K emails per day from gmail or yahoo. To send bulk mails you need to try best email sending software.
Basically email marketing specialists help clients build, manage and grow a profiled e-mail database and consult them on how to best drive maximum business value from their email data, while helping them increase their brand awareness and sales. You should consider going this route. Do you have your own database or are you looking at growing one?
