Yes, is FREE, and there is nothing wrong using FREE services. Only those who never spend effort looking for FREE stuff will always say “there is no free lunch under the sky“.

Refer to my “Email Marketing Blueprint“, I had mentioned that I experience email marketing during 2006, set up a few marketing campaigns along 2016 for a newly set up business, by sending a cold email and make a lucrative side income for that year. I am using FREE SMTP (Simple Mail Transfer Protocol) relay service as well for those campaigns, and basically, my investment is close to zero.

Well, as a newbie or startup, If you don’t have an additional budget to spend, try to reduce your OPEX, below is the list of 3rd party FREE SMTP Relay service that you must make use for your email marketing campaign

List of FREE SMTP Relay that I recommended

As a summary, if you are using desktop senders such as Sendblaster pro, Ultramailer or using self-hosted email systems such as Mailwizz, Interspire or any cloud base autoresponder, you can integrate all this SMTP and start your email marketing campaign free of charge.

If you look for email contact, you might want to find out how to scrape LinkedIn’s email from Google. Please note that SPAMMING will not help much, and I am always encouraged running a cold email campaign, mean only send targeted content to the targeted audience.

There is plenty more FREE SMTP relay service out there, some provide a high number of a free trial, I will constantly update this post for new SMTP that I personally tested 🙂

Update:, FREE 1000 Email
