Professional SMTP Service for Sending Email Newsletters

While your email list is small, you can use the SMTP server of your Internet Service Provider to send newsletters to your list. You can find the SMTP servers of the major ISP in this article.

When your list is grown, you need to find a professional SMTP server to be able to send a large volume of messages. G-Lock EasyMail7 can send emails through any third party SMTP server. In addition, you can use the SMTP settings of any email sender provider such as Amazon SES, SendGrid, Mandrill, etc. in G-Lock EasyMail7.

Amazon Simple Email Service (SES)

Amazon SES is a highly scalable and cost-effective bulk and transactional email-sending service for businesses and developers. In G-Lock EasyMail7 you can use the Amazon SES API as well as SMTP settings.

You can send emails through Amazon SES when:

  • you don't have your own SMTP server
  • you can't use your ISP mail server due to restrictions on bulk email sending
  • you can't afford high monthly fees charged by email service providers

The advantages of sending through Amazon SES are:

  1. subscription is quick and made on pay-as-you-go basis. You send bulk emails at an insanely low price, yet with no loss of quality in terms of deliverability. Compared to other ESP (email service providers) which can charge you up to $200 for 10 000 messages, Amazon SES is 200x cheaper — just $1 per 10 000 messages.
  2. high deliverability rate — your emails will pass SPF and Sender ID policy checks enforced by many ISPs and DKIM-sign.
  3. feedback loops — Amazon SES will send you an email once someone of your recipients reports your message as spam and G-Lock EasyMail7 built-in Bounce Handler will extract the recipient's email address from the feedback loop email in order you can take the recipient off your list.
