Viajar Barato Achieves a Decade of 100% Inbox Placement with Validity Sender Certification.
The challenge:
Frequent spam folder placement due to a lack of established best practices.
Viajar Barato relies on email marketing to share exclusive travel deals, helping Brazilians plan unforgettable holidays on a budget. Today, 40–50 percent of their sales come from email marketing campaigns.
However, Brazil is generally considered to be one of the most difficult countries for email deliverability. Brazilian senders see only a 76.1 percent average inbox placement rate (compared to the global average of 83.5 percent) according to Validity’s 2025 Email Deliverability Benchmark report.
“We didn’t have the best sending habits when we started— we were sending at a very high volume.”

Viajar Barato began to noticed a decline in their core email metrics, with many messages bouncing or being flagged as spam by mailbox providers.
The team realized they needed to take action if they wanted to continue relying on email as an outreach tool.
The solution:
Becoming one of the first Validity Sender Certification customers in Brazil.
Just a year after launching, Viajar Barato discovered Validity’s legacy email platform, Return Path, along with its team of deliverability experts. The Validity team quickly sprang into action, offering actionable tips to help Viajar Barato optimize their email campaigns, adjust sending volumes, and align with mailbox providers’ best practices.
With Validity’s help, Viajar Barato focused on cleaning up its large contact database and segmenting the audience strategically to ensure the right messages reached the right people at the right time.
By implementing best practices and leveraging the support of Validity’s deliverability experts, Viajar Barato soon qualified for Validity’s exclusive Sender Certification program. This program designates businesses as trusted senders in the eyes of mailbox providers, offering an added layer of deliverability assurance and helping senders reach more people.
“Qualifying for and implementing Sender Certification was actually pretty easy; having a team to ask questions and guide us through the process was really helpful.”

Sender Certification also provided Viajar Barato with valuable insights into their email metrics through robust daily reports. “Certification is a commitment and a constant effort to strengthen your email program day by day,” explained Barbosa. “We achieve this by closely monitoring our daily reports and collaborating with the Validity team to reach our goals.”
The results:
A consistent 100% inbox placement rate and a decade-long partnership.
More than 10 years later, Viajar Barato continues to use Sender Certification daily—and the results speak for themselves.
With Sender Certification, Viajar Barato consistently achieves a 99–100 percent inbox placement rate, a 24 percent uplift compared to the national average in Brazil. Additionally, they experience an estimated 22 percent revenue increase compared to non-Certified senders of similar size and email volume.
“We really value the consistency of our campaign metrics. That’s why we keep renewing our Sender Certification contract every time,” said Barbosa.
What’s next for Viajar Barato?
Barbosa shared that their solid foundation of email marketing success has enabled them to expand their outreach efforts into an omnichannel marketing strategy, incorporating platforms like WhatsApp.
“Validity has been a fantastic partner over the years. It’s not just about the results, which are consistently great, but also the community we’ve become part of. We’re always the first to publicly share how much we appreciate Validity, whether at conferences or in conversations.”
