02Pricing compared
Constant Contact has the lower listed starting price: $10.20 per month with 12-month prepayment, or $12 month to month. Its Lite plan includes 2 users, 1 automation template, 1 custom segment, and monthly sends up to 10 times the contact count. Standard is $29.75 per month annually or $35 monthly; Premium is $68 annually or $80 monthly.
GMass starts at $20 per month with annual billing paid upfront, or $29.95 month to month. Individual Standard includes unlimited emails, contacts, and campaigns, but no sequences or API access. Premium starts at $29 per month annually or $39.95 monthly and adds those features. Neither product lists a free plan. Compare the limits, not just the entry prices: GMass emphasizes unlimited email volume, while Constant Contact’s plans cap sends by contact count.
03Features and depth
Constant Contact covers more channels than GMass. Its platform includes email campaigns, SMS, social media tools, contact management, and event marketing, plus automation for welcome messages, birthdays, re-engagement, and abandoned carts. Lite has 1 automation template; Standard has 3; Premium includes unlimited custom automations and segments, as well as 500 SMS messages per month. SMS for Lite and Standard starts at $10 per month for 1–500 messages.
GMass is centered on sending from Gmail. It supports newsletters, announcements, cold campaigns, transactional messages, follow-ups, open and click tracking, Google Sheets data, and SMTP sending from apps. Plan limits matter: Individual Standard has no sequences or API access, while Individual Premium includes both. Inbox rotation is listed for Individual Professional and team plans, not Individual Premium. In short, Constant Contact suits a broader marketing program; GMass suits campaigns built around Gmail and follow-up workflows.
04Ease of use and learning curve
The easier starting point depends on where your work already happens. GMass runs inside Gmail, so its workflow is a closer fit for teams that already manage campaigns and correspondence there. Constant Contact is a separate, cloud-based marketing platform with tools for several channels, including email, SMS, social media, and events; that breadth may mean more areas to set up and manage.
The published reviews point to different cautions, not a definitive usability verdict. Constant Contact’s review notes reported editor problems and gives it a lower ease-of-use score than GMass. GMass’s review favors its Gmail-first fit but flags concerns about reliable tracking and low-cost automation. We’d weigh those notes against the specific workflow you need rather than treating either score as a guarantee.
