After the Twilio + Sendgrid acquisition, there has been a notable rise in complaints regarding the quality of support and issues with email deliverability.
I noticed many people are struggling with finding a better alternative so I wrote down a detailed comparison of Sendgrid alternatives.
SendGrid
👍 Sendgrid Pros
- One of the oldest and largest platforms for email delivery
- Free plan with basic functionality
- Advanced features for testing & email analytics
👎 Sendgrid Cons
- Occasional issues with deliverability reported by a large number of customers
- Bad support experience reported by many customers even on paid add-on plans
- You need to pay 2 separate plans for transactional emails and email marketing + email automation
- No premade email templates for transactional emails
- Complicated pricing with a lot of add-ons and extra fees for features
👍 Sidemail Pros
- All-in-one email platform
- 5-star rated support
- Fast and reliable email delivery
- Specialization in SaaS email delivery
- Quick integration, simple instructions, intuitive UI. The whole integration process takes about 30 minutes.
- Simple pricing, no add‑ons or extra fees
👎 Sidemail Cons
- Not offering a free plan
- “Different” approach. Sidemail's main focus is SaaS companies and online businesses – it simplifies the whole email game so they can focus on their business and not invest tons of resources in emails. However, this approach might not be suitable for others.
2 Mailgun (+ Mailjet)
👍 Mailgun Pros
- Pay-as-you-go option that you can activate before you find a monthly plan that fits your sending needs
- Solid functionality for managing transactional emails
- 99.99% uptime SLA offered even on lower plans
👎 Mailgun Cons
- Uncertain deliverability results
- Mixed customer support ratings
- You need to pay for 2 separate services for transactional emails and email marketing
3 Amazon SES
👍 Amazon SES Pros
- The cheapest alternative with a Pay-as-you-go pricing model
- The most robust architecture
- Fast and reliable email delivery
👎 Amazon SES Cons
- Do-it-yourself approach. It requires a lot of manual effort from your site to get things running.
- No support included
- No out-of-the-box features like template editor, premade templates, message history, email automation, or contact management
4 Postmark
👍 Postmark Pros
- Responsive support
- Solid delivery of transactional emails
- Unlimited team members
👎 Postmark Cons
- Missing functionality for email marketing and automation
- No visual editor. To create your templates, you have to write the code yourself.
- Support unavailable on weekends
5 Mailchimp (+ Mandrill)
👍 Mailchimp Pros
Advanced email marketing features
Landing page builder included
Solid free plan for email marketing
👎 Mailchimp Cons
- The most expensive alternative
- Uncertain transactional emails. Since the Mailchimp + Mandrill acquisition, it seems like the transactional part of the product is not receiving much focus and development.
- Previous data breach issues
