Am selling my mailerking life time license which means you don't have to pay any recurring fee's which are currently $50 per month. This license doesn't exist to buy anymore since it was only offered in the beginning. Its an awesome mailer with very high inbox rates.
Yes its still works. Recurring fee is 0 since its a lifetime membership which aren't being offered anymore
Can you detail more a bit? Like monthly email sending limit, IP addresses, server status, autoresponder included or not etc.
Its using email providers which are whitelisted. So your IP won't be shown when sending emails. Here a small review of mailerking http://recordit.co/uMuLhCTClq It has a very high inboxing rate using whitelisted email providers.
