Constant Contact vs SendGrid: What are the differences?

  1. Pricing: Constant Contact offers tiered pricing based on the number of contacts, starting from $20 per month. SendGrid, on the other hand, has a flexible pricing structure that depends on the volume of emails sent, starting from $14.95 per month. So, Constant Contact's pricing is based on the number of contacts, while SendGrid's pricing is based on the number of emails sent.

  2. Features: Constant Contact provides a range of features including email marketing, event management, surveys, and social media integration. In contrast, SendGrid primarily focuses on email delivery and provides features like email templates, email analytics, and email API. Therefore, Constant Contact offers a broader range of features beyond just email delivery compared to SendGrid.

  3. Automation: Constant Contact offers an easy-to-use automation feature that allows users to set up automated email campaigns based on triggers like sign-ups, purchases, or birthdays. SendGrid also provides automation capabilities, but it requires integration with external tools for setting up complex sequencing and workflows. So, Constant Contact offers a more seamless and built-in automation feature compared to SendGrid.

  4. Customer Support: Constant Contact offers phone, chat, and email support for all customers, including their basic plan. In contrast, SendGrid's customer support varies based on the plan level, with phone support available only for higher-tier plans. Therefore, Constant Contact provides more accessible customer support options for all users compared to SendGrid.

  5. Email Deliverability: SendGrid is a well-known and reputed email delivery service that specializes in providing high deliverability rates and reliable email infrastructure. Constant Contact, although also reliable, focuses more on holistic marketing solutions and may not have the same level of expertise and specialization in email deliverability as SendGrid. Thus, SendGrid has a stronger emphasis on ensuring deliverability compared to Constant Contact.

  6. Integration Options: Constant Contact integrates with a wide range of third-party tools and platforms, including popular CRM systems, e-commerce platforms, and event management tools. SendGrid also offers integrations but primarily focuses on email-related integrations with platforms like WordPress, Shopify, and Twilio. So, Constant Contact provides more diverse integration options beyond just email-related integrations compared to SendGrid.

In Summary, Constant Contact offers tiered pricing based on the number of contacts, provides a broader range of features beyond email delivery, offers an easy-to-use built-in automation feature, provides accessible customer support for all plans, focuses more on holistic marketing solutions rather than email deliverability specialization, and offers diverse integration options. On the other hand, SendGrid has flexible pricing based on email volume, specializes in high email deliverability rates, offers email-related integrations, and provides automation capabilities through external tool integration.

Advice on Twilio SendGrid, Constant Contact

Needs advice

For transactional emails, notifications, reminders, etc, I want to make it so writers/designers can set up the emails and maintain them, and then dynamically insert fields, that I then replace when actually sending the mail from code.

I think the ability to use a basic layout template across individual email templates would make things a lot easier (think header, footer, standard typography, etc).

What is best for this? Why would you prefer Mailgun, SendGrid, Mandrill or something else?

Needs advice

The problem I have is we are using mailchimp and not happy. We want to switch to mailster and are curious the easiest and best way to send emails with mailster.

The most important factors for me are ease of use, tracking.

I have only had experience with mailchimp, constant concact and streamsend. So ease of use is important.
