In their own words
turboSMTP
turboSMTP is a cloud SMTP service for sending email messages and newsletters, with statistical analysis for individual and aggregate messages. Its SMTP API supports transactional messages such as login confirmations, welcome messages, and receipts from a website or app. The dashboard tracks clicks and opens in real time, while listed tools manage bounces, spam, and unsubscribes. Deliverability features include smart routing, custom tracking domains, and email validation before campaigns. An email marketing tool can design, send, and track campaigns using turboSMTP delivery infrastructure. The service lists SMTP relay, email templates, delivery event webhooks, and a dedicated IP option; inbound email is not supported. It offers a free plan allowing 200 emails per day for the first six months. Basic costs €14.95 a month for 15,000 emails per month; Pro costs €79.95 a month for the same send limit and up to 100 subaccounts. Other listed plans sell email credits, which expire one year after purchase. Platforms include Android, API, iOS, and web. The maker advertises 24/7 multilingual support by phone, chat, and email.
Twilio Email API
Twilio Email API lets teams add transactional and marketing email to applications and cross-channel workflows through the Twilio Console. Requests use JSON and can address one or multiple recipients; emails can be scheduled up to seven days ahead. LiquidJS templates can personalize subject, text and HTML fields, while status reporting covers sent, delivered, undelivered, opened and failed messages. Real-time email logs and deliverability tools are included. Requests with attachments have a 10 MB limit and can include no more than 10,000 recipients. The listed pay-as-you-go plan costs nothing, billed per email sent at $0.0013 per email, with no monthly base fee, feature tiers or overage charges. A 30-day free trial offers 100 free emails per day. The API is listed for web and API use, with delivery by API; templates are listed as both and delivery logs are retained for 7 days. Twilio says Email and SendGrid are separate products built on the same email infrastructure, with SendGrid intended for high-volume transactional and marketing email.
