How to Choose the Right SMTP Service for Email Marketing
You can use EasyMail7 as a powerful front-end to email delivery vendors and SMTP relays. It enables you to effectively manage delivery INHOUSE or outsource it to multiple providers like Amazon SES, Mailgun, SparkPost, SendGrid, etc. You can quickly switch email sending services without losing your contact list, autoresponders, and other data.
You can segment your list by country, ISP or other factors and send from the SMTP or delivery service with the best deliverability – and the best chance for optimal revenue — to each segment.
There are multiple options to choose an SMTP relay or delivery service from:
free SMTP server (Gmail, Yahoo, AOL and others)
self-hosted or rented server (dedicated or VPS)
SMTP Server of Your ISP
ISPs often put email sending restrictions to control the level of email traffic being processed and ensure that their SMTP server will be available to support all of its users whenever they need to send email and to prevent spam from being sent through their system. Email sending limits establish a control to keep everything moving along smoothly.
So, using the ISP SMTP server is ok while you have a small email list. However, you'll want to visit your ISP's website and read their Acceptable Use Policy, Terms of Service, etc. to find out how many emails you can send. You'll find the list of the SMTP servers of the major Internet Service Providers at the end of this article.
Below are the email sending limits of some ISPs.
– Residential customers: 1,000 emails per day
– Business customers: 24,000 emails per day

Free SMTP Server
Many web-based email services such as Gmail, AOL, Yahoo, Hotmail support SMTP protocol, so you can use their SMTP server in G-Lock EasyMail7 to send newsletters. However, a free SMTP server for sending mass emails is not the best choice for two reasons: 1) just like ISPs, free webmail services have restrictions (usually 100-200 emails per day) for outgoing email, and 2) they watch your bounce rate carefully. If it's high, your account is blocked.
Below are the email sending limits of free email services.
– 500 emails per day when sending from their web interface
– 100 emails per day when sending from a desktop email client
Gmail email sending guidelines

Just like ISPs and free web-based email services, some hosting providers have email sending restrictions. So, visit your hosting provider website to read their email sending policy or contact them and ask if any sending restrictions exist for your plan.
Below are the email sending limits of some hosting providers.
– No limits for messages complying with the RackSpace Acceptable Use Policy

Commercial SMTP Services and Senders
Some companies specialize in providing SMTP servers. Typically they offer monthly plans based on the number of emails you need to send. But some companies such as Amazon SES have a “pay as you go” policy. And most of them have a free plan so you can test several email senders before deciding which one is the best for your needs. In G-Lock EasyMail7 you can use the SMTP settings of any email service or sender.

Dedicated Server or VPS (self-managed SMTP server)
As a dedicated SMTP server, you can use the free open source SMTP server from https://www.hmailserver.com/. You can install hmailserver to your local computer where G-Lock EasyMail7 Server is installed, or Windows Server, or Windows VPS and set EasyMail7 to use hmailserver as your SMTP server.
To effectively manage your in-house SMTP relay you will need to have a thorough understanding of e-mail delivery, including how to set up SPF, DKIM and ReverseDNS records. Most people can't do it without hiring an expert.
However, a dedicated in-house SMTP server is a good solution because the deliverability depends only on your sending practices and is not affected by other people who share the SMTP server with you.
Another good reason to choose a dedicated SMTP server is the cost effectiveness by a long shot. For those who want the cost efficiency accompanied by other features such as control, security, list and email management features, the hybrid email system EasyMail7 with a dedicated SMTP server offers a perfect balance — a cost-effective solution that does not compromise on quality.
EasyMail7 have a great deal of intelligence built-in, such as bounce handling, feedback loop analysis and automatic suppression lists which can protect your reputation by preventing redelivery to failed or complaining addresses.
Whatever SMTP server you choose EasyMail7 will work with it efficiently.
