About Difusiones Tecnológicas de Mercado

The DTM (Difusiones Tecnológicas de Mercado) communications group, specializing in market press and business lines based on new technologies, publishes 27 free real-estate magazines, five market newspapers, and two specialized information magazines, has a presence throughout Spain, and was founded in 1985.

Its 37 print publications reach a monthly circulation of 2,242,750 copies nationwide. Some of them are Tu Casa, a free real-estate magazine present in ten autonomous communities; Cambalache, Andalusia’s leading classified ads newspaper, as well as two specialized information magazines in the health and leisure fields, Consejos de tu farmacéutico and El visitante.

At the same time, for its online presence, it has 7 leading vertical portals in their respective sectors, some of them being: Tucasa.com, which has the country’s largest real-estate listings database as well as innovative services; Cambalache.es, the leader in classified ads in Andalusia; Consejos-e.com, a health and pharmacy website; and elvisitante.es, focused on tourism and leisure information for the province of Cádiz.

Goals of tucasa.com

The internal infrastructure they had used until then, based on their own SMTP server system, proved insufficient for the large volume of bulk email they needed to send — largely due to the success of their mass communications — so they needed to migrate to a high-performance platform in a very short time so their campaigns would not lose continuity.

Its large subscriber base and the multiple media outlets that are part of the group mean that getting their newsletters properly delivered to the main ISPs is a delicate task. After properly adapting the bulk email platform to their needs, it was essential that the more than 7.5 million monthly sends they generate had the reputation and design needed to handle such a volume of traffic.

Actions taken to improve tucasa.com’s deliverability

Aware of the urgency of restoring the client’s mass communications, Mailrelay‘s specialized staff got bulk email sending back up and running, with full guarantees, in record time — in under two weeks they were able to send out all their bulk mailings with a deliverability far higher than what they had enjoyed until then.

Likewise, the support provided by Mailrelay‘s technicians ensured the newsletters’ design was ideal, avoiding spam false positives and increasing their inbox penetration.

Mailrelay stands behind the quality of its product, so they were able to run a completely free real test of 1 million emails to check its performance and effectiveness.

They benefited from a custom IP warm-up plan, keeping the timing to a minimum so they could start sending bulk email at high speed in record time.

Result

The efficiency offered by Mailrelay‘s different operational areas gives us higher open rates than we had with our previous sending infrastructure, as well as letting us complete bulk sends of more than 1 million deliveries in very little time — something that used to take us several days and used to consume a great deal of our resources.

It’s worth noting that having a custom IP range and the IP warm-up plan mapped out by Mailrelay‘s support service is one of the main reasons they are able to send emails at high speed.

“Our powerful SMTP infrastructure couldn’t keep up with the huge sending needs we had from tucasa.com, so we turned to Mailrelay.
Not only do they have their own state-of-the-art infrastructure, they are also RIPE members (they manage their own IPs) and have agreements with major ISPs (such as Hotmail) so that our bulk sends receive preferential treatment on their incoming mail servers, and their sending speed is truly impressive. A reliable solution that lets our customer base grow, and one that gives us an excellent balance between emails sent and recipient response.”
